Question

A researcher wants to know if there is a difference between the mean amount of sleep that people get for various types of employment status. The table below shows data that was collected from a survey.

Unemployed	Part Time Worker	Full Time Worker
9	8	7
7	7	9
8	7	7
9	8	5

Assume that all distributions are normal, the three population standard deviations are all the same, and the data was collected independently and randomly. Use a level of significance of 0.05.

H₀: μ_Unemployed = μ_PartTime = μ_FullTime
H_a: At least two of the means are different from each other.
