Referring back to #3, you had a discussion with a friend who also coaches a high school team and he decides to replicate this experiment as much as possible. He wonders if age and year in school might account for some of the differences in free throw shooting ability. Thus, he conducts the same experiment except that he partitions the players into three groups: the first group is three sophomores; the second group is three juniors, and the third group is three seniors. He only had nine players that year. There were initially five more but they flunked statistics and became ineligible. The following results emerged. Groups 10 minutes per session

a.Set up hypotheses to determine if different practice sessions produce the same or different
b.Set up hypotheses to determine if the year in school produces the same or different number of free throws made.
c.Conduct the appropriate statistical tests and state all your conclusions.
d.What should be the coach’s recommendations?
e. What assumptions should have been made in this experiment?
f. How should these students have been assigned to the various experimental conditions?
