Suppose the Robert H. Smith School of Business at the University of Maryland would like to compare the starting salaries for both men and women who graduated with different majors. The following data show starting salaries for random students from the most recent graduating class. These data can also be found in the file starting salaries.xlsx.

a. Using α = 0.05, is there significant interaction ­between Factor A and Factor B (major and gender)?
b. Using a two way ANOVA and α = 0.05, does the ­major have an effect on a person€™s starting salary?
c. Using a two way ANOVA and α = 0.05, does gender have an effect on a person€™s starting salary?
d. If warranted, determine which means are significantly different using α = 0.05.
e. Construct an interaction plot for the major and gender factors.
