The college's athletic director wants to perform a test of H0: p = ⅔ versus Ha: p > ⅔, where p = the true proportion of the college's alumni who favor firing the coach.

A. Random? No, volunteer response sample Large Counts? Yes

B. Random? Yes Large Counts? fails

C. Both fails

D. Random? Random sample of 100 students Large Counts? np0 = 100(0.13) = 13 ≥ 10 and n(1-p0) = 100(0.87) = 87 ≥ 10
