A 95% confidence interval for the proportion of viewers of a certain reality television show who are over age 30 is (0.26, 0.35). The show's producers want to test the hypothesis

H0 : p = 0.25 against

Ha : p 0.25. Which of the following is an appropriate conclusion for them to draw?

(a) Reject H0 at both a = 0.01 and = 0.05.

(b) Reject H0 at = 0.05.

(c) Fail to reject H0 at = 0.05 but reject at = 0.01 .

(d) Reject H0 at = 0.10 , fail to reject for any smaller level.

(e) The producers do not have enough information to perform a test of significance.
