Two well-known aviation training schools are being compared using random samples of their graduates.It is found that 70 of 140 graduates of Fly-More Academy passed their FAA exams on the first try,compared with 104 of 260 graduates of Blue Yonder Institute.In a right-tailed test,the p-value is .0275,so at $\alpha$= .025 we should:
A) reject the hypothesis of equal proportions.
B) not reject the hypothesis of equal proportions.
C) change the $\alpha$ to .05 to get a rejection.

Question

Quizplus · Accepted Answer

Since the p-value is less than the level of significance of .025, we reject the null hypothesis of equal proportions and conclude that there is evidence that the proportion of graduates passing the FAA exam on the first try is higher at Blue Yonder Institute than at Fly-More Academy.
