The following three independent random samples are obtained from three normally distributed populations. The (dependent) numerical variable being compared is starting hourly wage, and the groups are the types of position (internship, co-op, work study).

Group 1: Internship	Group 2: Co-op	Group 3: Work Study
12.25	13	12.5
11.5	14	15
9.25	10.5	10.25
10	13.75	11.75
10.75	12.5	10.75
11	14.75	13
11	12.5	13
13	10.25	12.25
12.5	13.25	11

Use Exel to conduct a one-way ANOVA to determine if the group means are equal using α=0.01.

Create a side-by-side boxplot in Excel for these data. Use that and the numerical summary of sample data to answer the following questions.

Compute the Highest StandardDeviation/Smallest Standard = _________ (Rounded to 2 decimal places)

ANOVA summary statistics:

The F test statistic = _____-
(Rounded to 3 decimal places)
The p-value = _______
(Rounded to 4 decimal places)

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
