# Question: The Department of Labor DoL would like to investigate if

The Department of Labor (DoL) would like to investigate if there is a difference in the average number of hours worked per week by employees in the United States, China, and Sweden. DoL would also like to test if the age of the employee impacts the average number of hours worked per week. The following data show the number of hours that a random sample of employees worked last week in each country along with their age group. These data can also be found in the Excel file DOL. xlsx.

a. Using α = 0.05, is there a significant interaction between the age group and the country of the individual?

b. Using a two way ANOVA and α = 0.05, does the age group have an effect on the average number of weeks worked by the individual?

c. Using a two way ANOVA and α = 0.05, does the country have an effect on the average number of weeks worked by the individual?

d. If warranted, determine which means are significantly different using α = 0.05.

e. Construct an interaction plot for the age group and the country
