three student populations of interest. Is there sufficient evidence to conclude that the mean Hopkins score is not the same for the three student populations? Use α = 0.05.
The following data are from a study comparing three groups of college stu-
dents (soccer athletes, nonsoccer athletes, and a comparison group consisting of students
who did not participate in intercollegiate sports). The information below are scores from
the Hopkins Verbal Learning Test (which measures immediate memory recall).
Group Soccer Athletes Nonsoccer Athletes Comparison Group
Sample
Sample Standard Deviation 3.73 5.14 3.78
(a) Suppose that it is reasonable to regard these three samples as random
samples from the three student populations of interest. Is there sufficient evidence
to conclude that the mean Hopkins score is not the same for the three student
populations? Use α = 0.05.
(b) Use the Tukey-Cramer multiple comparison procedure to create an un-
derscore diagram of the three populations.
