Dave’s university has students from six different Canadian provinces. He surveys a representative sample of students to learn how many hours per week they study. Jim wants toknow if there are any differences among students from the six provinces in the average number of hours they study per week. If he chooses not to use an ANOVA,

a. How many unpaired two-sample t-tests will he need to conduct?

b. What would be his experimentwise Type I error if he makes each test have an α value of .05?

c. What would be his testwise Type I error if he performs a Bonferroni correction in order to maintain the experimentwise Type I error rate at .05?

d. What would be his testwise Type I error if he performs a Bonferroni correction in order to maintain the experimentwise Type I error rate at .01?

e. What would be the advantages of performing an ANOVA compared to performing a number of unpaired two-sample t-tests?
