The business college computing center wants to determine the proportion of business students who have laptop computers. If the proportion exceeds 35%, then the lab will scale back a proposed enlargement of its facilities. Suppose 300 business students were randomly sampled and 85 have laptops. Find the rejection region for the corresponding test using alpha = .10
Reject Ho if z>1.645 or z< -1.645
Reject Ho if z<-1.28
Reject Ho if z=1.28
Reject Ho if z>1.28
