(a) When performing an ANOVA with the data the alternative hypothesis is at least two of the restaurants have different mean delivery times.

(b)75.8

Analysis of variance. or ANOVA, is a statistical method that separate observed variance data into different components to use for additional tests. A one way ANOVA is used for three or more groups of data, to gain information about the relationship between the dependent and independent variables.

The ANOVA table shows how the sum of squares are distributed according to source of variation, and hence the mean sum of squares.

It is given that a pizza lover wants to compare the average delivery times.

Therefore the null hypothesis and alternate hypothesis implies that,

H₀ =  all restaurants have equal mean delivery time

Hₐ = at least two restaurants have different two deliveries

Hence the alternate hypothesis for performing an ANOVA with the data is at least two of the restaurants have different mean delivery times.

The alternate hypothesis (Hₐ) defines that there is a statistically important relationship between two variables. Whereas null hypothesis states that is no statistical relationship between the two variables.

\(\tt x^{\frac{4}{3}}=\sqrt[3]{x^4}\)

When dealing with fractional exponents, it's always useful to remember that the exponent can be written as a product of an integer and of a fraction that has the numerator equal to 1.

In general, this looks like this

ab=a⋅1b

This is important when dealing with fractional exponents because an exponent that takes the form 1b, like in the above example, is equivalent to taking the bth root.

x1b=b√x

The number of seconds that it would take the thermometer to hit the ground would be 22 seconds.

The equation for the height of the falling thermometer is h(t) = -16t² + initial height. We know that the initial height is 7,744 feet, and we want to find when the thermometer hits the ground, or when h(t) equals zero.

Setting h(t) to zero gives us:

0 = -16t² + 7744

Solve this equation for t:

16t² = 7744

t² = 7744 / 16 = 484

So, t = √(484) = 22 seconds

It will take 22 seconds for the thermometer to hit the ground.

What is Trigonometric Functions?

Trigonometry uses six fundamental trigonometric operations. Trigonometric ratios describe these operations. The sine function, cosine function, secant function, co-secant function, tangent function, and co-tangent function are the six fundamental trigonometric functions. The ratio of sides of a right-angled triangle is the basis for trigonometric functions and identities. Using trigonometric formulas, the sine, cosine, tangent, secant, and cotangent values are calculated for the perpendicular side, hypotenuse, and base of a right triangle.

As we can see in the right-angle triangle.

tan(54.5) = x/50  (from the right-angle triangle)

x = 50 * tan(54.5)

x = 70.09 ≈ 70.1 feet

Hence, the straight-line distance between penny and Lisa is 70.1 feet

The standard deviation of the ACT scores is approximately 4.2.

Standard deviation is a measure of the amount of variation or dispersion in a set of data values. It indicates how much the data values deviate, on average, from the mean (or average) of the data set. A higher standard deviation indicates greater variability or spread in the data, while a lower standard deviation indicates less variability or spread.

According to the given information:

To find the standard deviation of ACT scores, we can use the given information about the mean and the percentage of scores above a certain threshold.

Given:

Mean (μ) = 21.4

Percentage of scores above 26 = 15%

Since the distribution is approximately normal, we can use the Z-score formula to find the Z-score corresponding to the given percentage. The Z-score is the number of standard deviations a particular value is from the mean in a normal distribution.

Z-score formula:

Z = (X - μ) / σ

Where:

Z = Z-score

X = Value (in this case, 26)

μ = Mean (21.4)

σ = Standard deviation (to be found)

We can rearrange the formula to solve for σ:

σ = (X - μ) / Z

Substituting the given values:

X = 26

μ = 21.4

Z = Z-score corresponding to 15% (which can be found using a standard normal distribution table or a Z-score calculator)

Assuming a standard normal distribution table or calculator gives us a Z-score of approximately 1.04 for a percentage of 15%, we can plug in the values:

σ = (26 - 21.4) / 1.04

σ = 4.4 / 1.04

σ ≈ 4.2 (rounded to the nearest tenth)

So, the standard deviation of the ACT scores is approximately 4.2.

Answer:

This problem is asking you to use angle relationships (vertical angles, supplementary angles) to solve this problem.

Step-by-step explanation:

1. The vertical angles between ∠1 & ∠2 are equal, so find the value of x using an equation that sets them as equal to each other.

4x - 48° = x + 30°

2. These two vertical angles are supplementary to ∠1 & ∠2 on their corresponding sides (∠1 & x + 30°, ∠2 & 4x - 48°). Subtract the value of x from 180°, which is the degree of a straight line.

180° - x = ∠1

If a triangle has vertices at (-1,5), (4,2), and (1,2). The perimeter of the triangle is: 12.44 units.

To find the perimeter of the triangle, we need to calculate the distance between each pair of vertices and then add them up. We can use the distance formula to find the distance between two points:

Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Using this formula, we can calculate the three sides of the triangle:

Side 1: Distance between (-1,5) and (4,2)

= sqrt((4 - (-1))^2 + (2 - 5)^2)

= sqrt(5^2 + (-3)^2)

= sqrt(34)

Side 2: Distance between (4,2) and (1,2)

= sqrt((1 - 4)^2 + (2 - 2)^2)

= sqrt((-3)^2 + 0^2)

= 3

Side 3: Distance between (1,2) and (-1,5)

= sqrt((-1 - 1)^2 + (5 - 2)^2)

= sqrt((-2)^2 + 3^2)

= sqrt(13)

Now, we can add up the three sides to get the perimeter:

Perimeter = Side 1 + Side 2 + Side 3

= sqrt(34) + 3 + sqrt(13)

≈ 12.44 (rounded to two decimal places)

Therefore, the perimeter of the triangle is approximately 12.44 units.

The test statistic value lies to the right of the critical value. So we have sufficient evidence to reject the null hypothesis.

In null hypotheses, there is no relationship between the two phenomenons under the assumption or it is not associated with the group. And in alternative hypotheses, there is a relationship between the two chosen unknowns.

Students who take a statistics course are given a pre-test on the concepts and skills for the first chapter of a statistics course.

Then they are given a post-test once the professor has concluded lecturing on the material.

Pre-test and post-test scores for 4 students in an elementary statistics class are given below.

Then we have

\(\mu _d = \mu _{post} - \mu _{pre}\)

Then the null hypotheses and alternative hypotheses will be

H₀: \(\mu _d = 0\)

Hₐ: \(\mu _d > 0\)

Then the test statistic will be

\(\rm \overline{x} _d = \dfrac{\Sigma x_d}{n} = \dfrac{15+12+10+1}{4}\\\\\overline{x} _d = 9.5\)

Then

\(\rm S_d = 6.02\)

The test statistic value is given by

\(\rm t = \dfrac{\overline{x} _d }{\dfrac{S_d}{\sqrtn}} \\\\t = \dfrac{9.5}{\dfrac{6.02}{\sqrt4}}\\\\t = 3.16\)

Since this is a right-tailed test, so the critical value is given by

\(\rm t_{n-1}(\alpha ) = t_3 (0.05) = 2.353\)

Since the test statistic value lies to the right of the critical value. So we have sufficient evidence to reject the null hypothesis.

Hence, we can conclude that \(\mu _d > 0\) that is test scores have improved.
