A random sample of women is obtained, and each person in the sample is asked if she would purchase a new shoe model. The new shoe model would be successful in meeting corporate profit objective if more than 25% of the women in the population would purchase this shoe model. The following hypothesis test can be performed at a level of α = 0.03 using p` as the sample proportion of women who said yes.
H0: P ≤ 0.25
H1: P > 0.25
What value of the sample proportion, p`, is required to reject the null hypothesis, given the following sample sizes?
a. n = 400
b. n = 225
c. n = 625
d. n = 900
