A newspaper wants to take a poll about which candidate voters prefer for President. Identify any bias in each sampling method.At a high school, 30% of the students buy class rings. You select five students at random. Find P (exactly two buy rings) and P (at least two buy rings).
Answers
The probability of exactly two students buying rings is 0.3087, and the probability of at least two students buying rings is 0.8369.
The bias in this sampling method is that it only involves students from one specific high school. This may not accurately represent the preferences of voters in the entire population.
Out of the five students selected at random, the probability of exactly two buying rings can be calculated using the binomial probability formula.
The formula is P(X = k) = (nCk) * \(p^k*(1-p)^(n-k)\), where n is the number of trials, k is the number of successes, p is the probability of success, and (nCk) is the binomial coefficient.
In this case, n = 5 (as five students are selected), k = 2 (as we want exactly two students to buy rings), and p = 0.3 (as 30% of the students buy rings).
Plugging these values into the formula,
we get P(X = 2) = (5C2) * \(0.3^2*(1-0.3)^(5-2).\)
Simplifying this equation, we find P(X = 2) = 0.3087.
To calculate the probability of at least two students buying rings, we need to find the sum of probabilities for two, three, four, and five students buying rings.
Using the same formula, but with k ranging from 2 to 5, we can calculate these probabilities and add them together.
The total probability comes out to be P(X ≥ 2) = 0.8369.
Thus, the probability of exactly two students buying rings is 0.3087, and the probability of at least two students buying rings is 0.8369.

solve (x+21)+(2x+9)=90
Answers
Answer:
The answer is x=20
Step-by-step explanation:
Answer:
x = 20
Step-by-step explanation:
(x+21)+(2x+9)=90
x + 21 + 2x + 9 = 90
combine numbers on left side:
x + 30 + 2x = 90
combine x terms on left side:
3x + 30 = 90
subtract 30 from both sides:
3x + 30 -30 = 90 - 30
3x = 60
divide both sides by 3:

x = 20
suppose a research report states that the result of a between subjects one-way anova is f (3, 32) = 3.47 should the researcher reject the null hypothesis if using alpha = .05
Answers
Based on the given information, the researcher should not reject the null hypothesis if using an alpha level of 0.05.
In hypothesis testing, the null hypothesis is typically assumed to be true until there is sufficient evidence to reject it. To determine whether to reject the null hypothesis, researchers often compare the calculated F-value from an ANOVA test with the critical F-value. The critical F-value is based on the significance level (alpha) chosen for the test. In this case, the given F-value is 3.47 with degrees of freedom (3, 32), indicating that there are three groups and a total of 32 observations. To make a decision, the researcher needs to compare the calculated F-value to the critical F-value. If the calculated F-value is greater than the critical F-value, the null hypothesis is rejected. However, if the calculated F-value is less than or equal to the critical F-value, the null hypothesis is not rejected. Since the critical F-value corresponding to alpha = 0.05 is not provided in the question, we cannot determine whether the null hypothesis should be rejected.

Answer:
3840
Step-by-step explanation:
if 120 divided by 750 is 16% then 16% of 24000 is 3840
Number of students out of surveyed students who live within 500 miles
= Total number of students surveyed - Number of students who live 500 miles away or more
= 750 - 120
= 630
Ratio of number of students surveyed to the number of students out of them living within 500 miles
= 750:630
= 25:21
Let the actual number of students living within 500 miles be x.
If the students are surveyed randomly then,
Ratio of number of students surveyed to the number of students out of them living within 500 miles = Ratio of actual number of students to the number of actual students living within 500 miles
=> 25:21 = 24000:x
=> 25/21 = 24000/x
=> x = (24000×21)/25
=> x = 504000/25
=> x = 20160
So, the number of actual students who live within 500 miles is 20160.

Sonya, who is paid time and a half for hours worked in excess of 40 hours, had gross weekly wages of $345 for 44 hours worked. What is her regular hourly rate?
Answers
Answer:
$7.5/hour
Step-by-step explanation:
Sonya is paid time and half for hours worked in excess of 40 hours
She has a gross weekly wages of $345 for 44 hours
Let y represent sonya's hourly rate
Since she is paid one and half then it can be represented as 1.5y
Sonya is suppose to work for a period of 40 hours, this means that she has 4 overtime hours
Therefore Sonya regular hourly rate can be calculated as follows
40y + 4(1.5y) = 345
40y + 6y = 345
46y= 345
y = 345/46
y= 7.5
Hence Sonya's regular hourly rate is $7.5/hour

Determine which statistical technique you will employ to measure the quality characteristics of your organization. provide examples to support the rationale.
Answers
To measure the quality characteristics of an organization, one statistical technique that can be employed is Statistical Process Control (SPC).
SPC is a method used to monitor and control processes to ensure they are operating within predetermined limits. It involves the use of control charts to analyze process data and identify any variations that may occur.
SPC provides a visual representation of process performance over time, allowing organizations to identify and address any issues that may affect quality. Control charts, such as the X-bar and R charts or the X-bar and S charts, are commonly used in SPC to monitor the mean and variability of a process.
For example, let's say a manufacturing company wants to measure the quality characteristics of its production line. The company can collect data on key quality indicators, such as product dimensions or defects, at regular intervals. Using SPC, the company can create control charts to track these measurements over time. If the data points fall within the control limits, it indicates that the process is stable and in control. However, if there are any data points outside the control limits or any patterns or trends observed, it may indicate a problem that requires investigation and corrective action.

What is triangle ?
Triangle can be defined in which it consists of three sides , three angles and sum of three angles is always 180 degrees.
In the given triangle ,
Triangle STU ,
T = 90
S = 69
So, U = 180 - 90-69
U = 180 - 159
U = 21
And US = 10
sin69 = TU/US
sin69 = TU / 10
0.93 = TU/ 10
93 / 100 = TU / 10
93/10 = TU
TU = 9.3
So, in the triangle
as per pythagores theorem ,
SU^2 = ST^2 + TU^2
10*10 = x*x + 9.3*9.3

b. 5.6
c. 6.8
d. 7.6

Answers
The sample variance for the given data is 4.4 minutes. This corresponds to option e. in the list of choices provided.
The sample variance is a measure of how much the individual data points in a sample vary from the mean.
It is calculated by finding the average of the squared differences between each data point and the mean.
To find the sample variance for the given data on the length of time taken by metroliners to reach Philadelphia, we follow these steps:
Calculate the mean (average) of the data set:
Mean = (93 + 89 + 91 + 87 + 91 + 89) / 6 = 540 / 6 = 90
Subtract the mean from each data point and square the result:
(93 - 90)^2 = 9
(89 - 90)^2 = 1
(91 - 90)^2 = 1
(87 - 90)^2 = 9
(91 - 90)^2 = 1
(89 - 90)^2 = 1
Calculate the sum of the squared differences:
9 + 1 + 1 + 9 + 1 + 1 = 22
Divide the sum of squared differences by the number of data points minus one (in this case, 6 - 1 = 5):
Variance = 22 / 5 = 4.4

The number of possible numbers in the given format is 7 × 9 × 9 × 9 × 10⁴, there are 567,000,000 possible telephone numbers in the given format.
In the given telephone number format, there are 7 digits, denoted by abc - xxxx.
The digit a is restricted to the range 3 - 9, so there are 7 possible choices for a.
The digits b and c can be any digit from 1 - 9, so there are 9 possible choices for each of them.
For the remaining digits x, they can be any digit from 0 - 9, resulting in 10 choices for each x. Since there are 4 x's in the format, we have 10⁴ choices for these digits.
To calculate the total number of possible telephone numbers, we multiply the number of choices for each digit: 7 × 9 × 9 × 9 × 10⁴ = 7 × 9³ × 10⁴ = 7 × 9⁴ × 10⁴ = 7 × 9⁴ × (10²)² = 7 × (9²)² × (10²)² = 7 × 81 × 10⁴ × 10⁴ = 7 × 81 × (10⁴)² = 7 × 81 × 10⁸ = 567 × 10⁸ = 567,000,000.

A circle has a radius of 8 cm. A good estimate for the circumference of the circle is 24 cm. TrueFalse
Answers
False. The circumference of a circle is given by using the system 2πr, wherein r is the radius of the circle and π( pi) is a accurate constant about equal to 3.14.
If the radius of the circle is 8 cm, then the precise circumference is:
C = 2πr = 2 × 3.14 × 8 ≈ 50.24 cm
Consequently, the given estimate of 24 cm is extensively decrease than the real value of the circumference. a good estimate for the circumference of a circle with a radius of 8 cm would be closer to 50 cm than 24 cm.
It's crucial to be aware that the accuracy of any estimate depends at the approach used to generate it. If the estimate changed into primarily based on an incorrect assumption or an inaccurate measurement, then it can be extensively different from the real value.
