The following is used for questions 25, 26, and 27. In a random sample of 200 adults, 54 say they are in favor of outlawing cigarettes. Let p be the proportion of all adults who are in favor of outlawing cigarettes. One is interested for the following hypotheses: Ho : p = 0.23 versus H. : p #0.23. 25. The standardized test statistics is about (a) -1.34. (b) -1.27 (c) 1.27 (d) 0.27 (e) 1.34 26. The P-value of this test is (a) 0.0901 (b) 0.1802 (c) 0.9099 (d) 0.8980 (e) 1.8198 27. With the significance level a of 0.01, find the rejection region.

At a high school debate tournament, half of the teams were asked to wear suits and ties and the rest were asked to wear jeans and T-shirts. The results are given in the table below. In order to test the claim at the 0.05 level that the proportion of wins is the same for teams wearing suits as for teams wearing jeans, what would the null hypothesis be? Win Loss Suit 22 28 T-Shirt 28 22 O A. The proportions of wins is different for teams wearing suits as for teams wearing jeans. O B. The proportions of wins is the same for teams wearing suits as for teams wearing jeans. O C. The mean number of wins is the same for teams wearing suits as for teams wearing jeans. O D. The mean number of wins is different for teams wearing suits as for teams wearing jeans.
According to the most recent General Social Survey, 70% of adults watch TV nightly. A researcher believes that the proportion of college students who watch TV nightly is less than this. To test this claim the research samples 400 college students and finds that 276 watch TV nightly. At the 0.05 level of significance does this data provide evidence to suggest that the proportion of college students who watch TV nightly is less than 70%? Select the correct conclusion for the hypothesis test: Question 12 options: Fail to reject the null hypothesis because the p-value is less than the level of significance. Fail to reject the null hypothesis because the p-value is greater than the level of significance. Reject the null hypothesis because the p-value is less than the level of significance. Reject the null because the p-value is greater than the level of significance.
Males and females were asked what they would do if they received a $100 bill in the mail that was addressed to their neighbor, but had been incorrectly delivered to them. Of the 70 males sampled, 55 said yes they would return it to their neighbor. Of the 130 females sampled, 120 said yes. The overall question is: Is this sufficient evidence to say that the two true proportions are different? Choose the best null and alternative hypothesis for this test. O Null: (p1 - p2) = 0 vs Alternative (p1 - p2) > O. O Null: (p1 - p2) = 0 vs Alternative (p1 - p2) not = 0.
