9.A professor wants to know whether critical-thinking skills change as a student progresses through college. He compares critical-thinking skills for a group of students at three time points: during the students' first semester, fifth semester, and eighth semester. The results of his study are as follows: F(2, 40) = 5.25, p < .05. What does he conclude?

a) He rejects the alternative hypothesis.

b) He fails to reject the null hypothesis.

c) He fails to reject the alternative hypothesis.

d) He rejects the null hypothesis.

Answer 1

5. The correct answer is Option D. The value of F is 2.

6. The correct answer is Option D. At least one population mean is different from at least one of the others.

7. The correct answer is Option C. The value should be 5.42.

8. The correct answer is Option A. Mean of group 1 = 10 and Mean of group 2 = 15 would be considered significant.
