Question

The following three independent random samples are obtained from three normally distributed populations with equal variances. The dependent variable is starting hourly wage, and the groups are the types of position (internship, co-op, work study). We are testing the claim that position is a factor in starting salaries for new college graduates. at α=0.2α=0.2 given the following data

Group 1: Internship	Group 2: Co-op	Group 3: Work Study
9.75	8.5	12.75
14.75	10.75	11.25
14.5	9.75	11.75
13.5	11	11.5
15.5	10.25	11
11.75	11	12.5
10.25	11.25	12.75
11.75	11.75	10
9.5	8.75	12

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
