The mayor of a town saw an article that claimed the national unemployment rate is 8%. They wondered if this held true in their town, so they took a sample of 200 residents to test H_0 : p = 0.08 versus H_a : p != 0.08, where p is the proportion of residents in the town that are unemployed. The sample included 22 residents who were unemployed.Identify the correct test statistic for this significance test to one decimal place.
Answers
Answer:
Z = \(\frac{0.11-0.08}{\sqrt{0.08*0.92/200} }\) = 1.6
we reject the Null hypothesis
Step-by-step explanation:
The correct test statistic
Assume :
Null Hypothesis : H_0 : p = 0.08
Alternative hypothesis : H_a : p ≠ 0.08
p = proportion of residents that are unemployed
x = unemployed residents = 22
n = sample size = 200
To get the sample of the population that is unemployed we use this equation
\(p = \frac{X}{n}\) = 22 / 200 = 0.11
now we apply the test of of significance of single proportion
= Z = \(\frac{p - P}{\sqrt{pq/n} }\)
therefore Z = \(\frac{0.11-0.08}{\sqrt{0.08*0.92/200} }\) = 1.6
Therefore we reject the Null hypothesis
Testing the hypothesis, it is found that the test statistic used is z = 1.6.
At the null hypothesis, it is tested if the proportion is of 8%, that is:
\(H_0: p = 0.08\)
At the alternative hypothesis, it is tested if the proportion is different of 8%, that is:
\(H_1: p \neq 0.08\)
The test statistic is given by:
\(z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}\)
In which:
\(\overline{p}\) is the sample proportion. p is the proportion tested at the null hypothesis. n is the sample size.For this problem, the parameters are: \(p = 0.08, n = 200, \overline{p} = \frac{22}{200} = 0.11\)
Hence, the value of the test statistic is:
\(z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}\)
\(z = \frac{0.11 - 0.08}{\sqrt{\frac{0.08(0.92)}{200}}}\)
\(z = 1.6\)

1. The two vectors parallel to the plane: Vector AB = (8, -5, 4) and Vector AC = (0, 7, 6)
2. The vector perpendicular to the plane is (-58, -48, 56).
How do we calculate for vectors parallel and perpendicular to the plane?
To find the vectors parallel to the plane, we begin by finding the vectors AB and AC.
Vector AB = B - A = (11 - 3, -5 - 0, 2 - (-2)) = (8, -5, 4)
Vector AC = C - A = (3 - 3, 7 - 0, 4 - (-2)) = (0, 7, 6)
To find a vector perpendicular to the plane, we can take the cross product of the two vectors we found in part (a), AB and AC.
AB × AC = (AB_y * AC_z - AB_z * AC_y, AB_z * AC_x - AB_x * AC_z, AB_x * AC_y - AB_y * AC_x)
If we insert the figures, it will be
= ((-5) x 6 - 4 x 7, 4 x 0 - 8 x 6, 8 x 7 - (-5) x 0)
= (-30 - 28, -48, 56)
= (-58, -48, 56)
Consider the plane determined by the points A(3, 0, -2), B(11, -5, 2) and C(3, 7, 4).

Using the most conservative estimate, what sample size would be required to reduce the margin of error to 2 percentage points?
Answers
Answer:
The sample size required is 2188.
Step-by-step explanation:
The (1 - α)% confidence interval for the population proportion is:
\(CI=\hat p\pm z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}\)
The margin of error for this interval is:
\(MOE= z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}\)
The information provided is:
X = 162
n = 462
MOE = 0.02
Assume the confidence level as 95%.
Compute the sample proportion as follows:
\(\hat p=\frac{X}{n}=\frac{162}{462}=0.351\)
The z-critical value for 95% confidence interval is:
\(z_{0.025}=1.96\)
Compute the sample size required as follows:
\(MOE= z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}\)
\(n=[\frac{z_{\alpha/2}\times \sqrt{\hat p(1-\hat p)}}{MOE}]^{2}\)
\(=[\frac{1.96\times\sqrt{0.351(1-0.351)}}{0.02}]^{2}\\\\=2187.781596\\\\\approx 2188\)
Thus, the sample size required is 2188.

How could expanded land acreage and pricing be viewed as some to be a bad thing
for the recovering Great Plains?
Answers
Increased land prices and acreage on the Great Plains could be seen as negative owing to potential ecological impact, as a disruption for Traditional communities and unsustainable resource use.
Why expanded land acreage and pricing in Great plains is considered negative?Ecological impact: Increased land acreage and price may cause habitat loss, biodiversity loss, soil erosion, and water pollution, all of which might be detrimental to the area's natural ecosystem.Disruption of traditional farming and ranching communities: Increasing land prices and greater parcel sizes may make it harder for small-scale farmers and ranchers to compete, which might result in the consolidation of land ownership and the eradication of traditional farming and ranching communities.Unsustainable resource use: Increasing land area might result in more water being used for irrigation, thereby worsening the Great Plains' water shortage problems.Loss of grasslands: The Great Plains are renowned for their distinctive grassland ecosystems, which are essential for biodiversity and carbon sequestration. More land being used for construction or agriculture might lead to the extinction of grasslands, which would have detrimental ecological effects.Degradation of the soil: Intensive agricultural techniques, such as monoculture and extensive chemical usage, may result in the loss of fertility and accelerated erosion of the soil. Long-term, this can have a negative effect on the sustainability and production of agricultural areas.Increased use of chemical inputs: Increasing land area may result in higher usage of chemical pesticides and fertilisers, which might impact regional ecosystems and contribute to environmental degradation.Danger of overproduction: Increased land acreage and pricing may lead to overproduction of agricultural products, which might lead to unstable prices, unstable farmer livelihoods, and potential market saturation.Potential for land speculation: Increasing land prices may encourage speculative investment, which might result in land being bought and retained for financial gain rather than for productive use. This could push up land prices even more and restrict access to land for local farmers and ranchers.Risks to wildlife and biodiversity: Include habitat fragmentation, the loss of wildlife corridors, and the displacement of native species, all of which might have an effect on the biodiversity and animal populations of the area.Learn more about land acreage and pricing here:

Reuben made a shirt using 7/8yards of red fabric and 1/4yards of yellow fabric. How many more yards of red fabric did Reuben use?
Answers
Answer and Step-by-step explanation:
To find out how many more yards of red fabric Reuben used, we need to subtract the amount of yellow fabric from the amount of red fabric. Since the two fractions have different denominators, we need to find a common denominator before subtracting them. The least common multiple of 8 and 4 is 8, so we can rewrite both fractions with a denominator of 8:
7/8 - 1/4 = 7/8 - (1/4) * (2/2) = 7/8 - 2/8 = (7 - 2)/8 = 5/8
So, Reuben used 5/8 yards more red fabric than yellow fabric.
By using graphical method, find optimal solution of the problem max z = 3x + y s.t 2x - y ≤ 5 -x + 3y ≤ 6 x ≥ 0, y ≥ 0
Answers
By analyzing the graph and evaluating the objective function at each vertex of the feasible region, we can find the optimal solution, which is the vertex that maximizes the objective function z = 3x + y.
To find the optimal solution of the given problem using the graphical method, we need to plot the feasible region determined by the given constraints and then identify the point within that region that maximizes the objective function.
Let's start by graphing the constraints:
1. Plot the line 2x - y = 5. To do this, find two points on the line by setting x = 0 and solving for y, and setting y = 0 and solving for x. Connect the two points to draw the line.
2. Plot the line -x + 3y = 6 using a similar process.
3. The x-axis and y-axis represent the constraints x ≥ 0 and y ≥ 0, respectively.
Next, identify the feasible region, which is the region where all the constraints are satisfied. This region will be the intersection of the shaded regions determined by each constraint.
Finally, we need to identify the point within the feasible region that maximizes the objective function z = 3x + y. The optimal solution will be the vertex of the feasible region that gives the highest value for the objective function. This can be determined by evaluating the objective function at each vertex and comparing the values.
Note: Without a specific graph or additional information, it is not possible to provide the precise coordinates of the optimal solution in this case.

When Tyee runs the 400 meter dash, his finishing times are normally distributed with a mean of 61 seconds and a standard deviation of 1.5 seconds. If Tyee were to run 39 practice trials of the 400 meter dash, how many of those trials would be faster than 62 seconds, to the nearest whole number?
Answers
To find out how many of the 39 practice trials would be faster than 62 seconds, we need to calculate the proportion of trials that fall within the range of more than 62 seconds.
We can use the z-score formula to standardize the values and then use the standard normal distribution table (also known as the z-table) to find the proportion.
The z-score formula is:
z = (x - μ) / σ
Where:
x = value (62 seconds)
μ = mean (61 seconds)
σ = standard deviation (1.5 seconds)
Calculating the z-score:
z = (62 - 61) / 1.5
z ≈ 0.6667
Now, we need to find the proportion of values greater than 0.6667 in the standard normal distribution table.
Looking up the z-score of 0.6667 in the table, we find the corresponding proportion is approximately 0.7461.
To find the number of trials faster than 62 seconds, we multiply the proportion by the total number of trials:
Number of trials = Proportion * Total number of trials
Number of trials = 0.7461 * 39
Number of trials ≈ 29.08
Rounding to the nearest whole number, approximately 29 of the 39 practice trials would be faster than 62 seconds.

The solution to the system of equation is (0.3, -8.9). This shows that the ordered pair that is the solution to the system lies in Quadrant IV.
Given the systems of equations
y=−43x+4

\(-43x + 4 = -23x - 2\)
Collect the like terms
\(-43x+23x=-2-4\\-20x=-6\\x=\frac{3}{10}\)
Substitute \(x=\frac{3}{10}\) into the value of y above to have:
\(y=-23(\frac{3}{10} )-2\\y=\frac{-69}{10}-2\\y=-6.9-2\\y=-8.9\)
Hence the solution to the system of equation is (0.3, -8.9). This shows that the ordered pair that is the solution to the system lies in Quadrant IV.

The arrow is at a height of 48 ft after approx. ___ s and after ___ s.
Answers
The arrow is at a height of 48 ft after approx. 3 - √6 s and after 3 + √6 s.
To find the time it takes for the arrow to reach a height of 48 ft, we can use the formula for the height of the arrow:
s = v0t - 16t^2
Here, s represents the height of the arrow, v0 is the initial velocity, and t is the time.
Given that the initial velocity, v0, is 96 ft/s and the height, s, is 48 ft, we can set up the equation:
48 = 96t - 16t^2
Now, let's solve this equation to find the time it takes for the arrow to reach a height of 48 ft.
Rearranging the equation:
16t^2 - 96t + 48 = 0
Dividing the equation by 16 to simplify:
t^2 - 6*t + 3 = 0
We now have a quadratic equation in the form of at^2 + bt + c = 0, where a = 1, b = -6, and c = 3.
Using the quadratic formula:
t = (-b ± √(b^2 - 4ac)) / (2a)
Plugging in the values:
t = (6 ± √((-6)^2 - 413)) / (2*1)
t = (6 ± √(36 - 12)) / 2
t = (6 ± √24) / 2
Simplifying the square root:
t = (6 ± 2√6) / 2
t = 3 ± √6
Therefore, the arrow reaches a height of 48 ft after approximately 3 + √6 seconds and 3 - √6 seconds.
In summary, the arrow takes approximately 3 + √6 seconds and 3 - √6 seconds to reach a height of 48 ft, assuming an initial velocity of 96 ft/s.

Let's focus on point C. Right now, it is located at (1,1). If we move it 3 units to the right, then it arrives at (4,1). We have the correct x coordinate, but the y coordinate is not correct. We're one unit below our target, which is where Z is located.
But what we could do is instead of moving 3 units to the right, we can move 1 unit to the right. Point C will go from (1,1) to (2,1). Now apply a dilation with scale factor 2. This will multiply the coordinates by 2. So (2,1) doubles to (4,2) which is exactly where point Z is located. This process is effectively trial and error, so we got a bit lucky and didn't have to do much work to move C to Z.
-----------------
We'll do the same steps for points A and B to see if we can get them to move to X and Y respectively.
Point A is located at (2,3). Shifting one unit to the right lands us on (3,3). Double the coordinates to get to (6,6). This is where point X is located.Point B is at (3,1). It moves to (4,1) after shifting one unit to the right. Then it moves to (8,2) when we double the coordinates, and this is where point Y is located.So the process of "shift one unit to the right, double the coordinates" works for points A and B also.
Keep in mind that the order of the transformations is important. We cannot double the coordinates first, and then shift one unit to the right. If we did that, then point C would move to (3,2) which is not where point Z is located.
