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 a = .10.
Choose one answer.
a. Reject H0 if z > 1.28.
b. Reject H0 if z < -1.28.
c. Reject H0 if z > 1.645 or z < -1.645.
d. Reject H0 if z = 1.28.
