In a large northwestern university, an SRS of 100 entering freshmen in 1988 found that 20 finished in the bottom third of their high school class. Admission standards at the university were tightened in 1990. In 1992 an SRS of 100 entering freshmen found that 10 finished in the bottom third of their high school class. Letting p1and p2be the proportion of all entering freshmen in 1988 and 1992, who graduated in the bottom third of their high school class?
Is there evidence that the proportion of freshmen who graduated in the bottom third of their high school class in 1992 has been reduced, as a result of the tougher admission standards adopted in 1990, compared to the proportion in 1988? To determine this, you test the hypotheses:
H0:p1=p2
HA:p1>p2
What is the p-value of your test?
A)Between 0.10 and 0.05
B) Between 0.01 and 0.001
C) Below 0.001
D) Between 0.05 and 0.01
E) None of the above

An SRS of 25 faculty members at a large southeastern university found that 10 felt that the university was supportive of female and minority faculty. An independent SRS of 20 female faculty found that 5 felt that the university was supportive of female and minority faculty. Let p1and p2represent the proportion of all male and female faculty at the university who felt that the university was supportive of female and minority faculty at the time of the survey.
Is there evidence that the proportion of male faculty members was supportive of female and minority faculty is larger than the corresponding proportion for female faculty members? To determine this, you test the hypotheses:
H0:p1=p2
HA:p1>p2
What is the p-value of your test?
A) Between 0.05 and 0.01
B) Larger than 0.05
C) Below 0.001
D) Between 0.005 and 0.001
