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 H, : p = 0.25 against H:p#0.25. Which of the following is an appropriate conclusion for them to draw? (a) Reject H, at both a = 0.01 and a = 0.05. (b) Reject H, at a = 0.05. (c) Fail to reject H, at a = 0.05 but reject at a = 0.01. (d) Reject H, at a = 0.10 , fail to reject for any smaller a level. (e) The producers do not have enough information to perform a test of significance.
