In a survey of 175 females who recently completed high school, 76% were enrolled in college. In a survey of 150 males who recently completed high school, 72% were enrolled in college. At a = 0.05, can you reject the claim that there is no difference in the proportion of college enrollees between the two groups? Assume the random samples are independent. Complete parts (a) through (e). O A. Ho: P1 #P2 Ha: P1 = P2 O B. Ho: P1 <P2 Ha: P1 2 P2 O E. Ho: P1 2P2 C. Ho: P1 sP2 Ha: P1 > P2 OF. Ho: P1 = P2 O D.
