A Pew Research Center poll asked randomly selected subjects if they agreed with the statement that "It is morally wrong for married people to have an affair". Among the 578 women surveyed, 444 agreed with the statement. Among the 603 men surveyed, 506 agreed Use a .02 significance level to test the claim that the percentage of women who agree with the statement is different from the percentage of men who agree with it. Find the pooled estimate. State the null and alternative hypothesis Find the test statistic Find the critical values Find the P-value Provide the 98% confidence interval for the difference of the proportions Does it appear to be a difference in the way women and men feel about this issue?

Suppose that in random selection of 100 colored candies, 20% of them are blue. The candy company claims that the percentage of blue candies is equal to 26%. Use a 0.01 significance level to test that claim. Identify the null and alternative hypotheses for this test. Choose the correct answer below. OA. Ho: P# 0.26 H₁: p= 0.26 B. Ho: p=0.26 H₁:p # 0.26 OC. Ho: p= 0.26 H₁: p > 0.26 O D. Ho: p= 0.26 H₁: p<0.26 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) ←

An annual survey of first-year college students asks 276,000 students about their attitudes on a variety of subjects. According to a recent survey, 51% of first-year students believe that abortion should be legal. Use a 0.05 significance level to test the claim that over half of all first-year students believe that abortion should be legal. Formulate the null and alternative hypotheses. Choose the correct answer below. .... A. Ho:p=0.5 O A. O B. Ho: p=0.5 Ha:p#0.5 Ha:p0.5 Find the test statistic. (Round to two decimal places as needed.) Find the P-value for the found test statistic. P-value = |(Round to four decimal places as needed.) State the conclusion. Choose the correct answer below. O A. Reject Ho. There is sufficient evidence to support the claim that over half of all first-year students believe that abortion should be legal. B. Do not reject Ho. There is sufficient evidence to support the claim that over half of all first-year students believe that abortion should be legal. C.…

Suppose 239 subjects are treated with a drug that is used to treat pain and 52 of them developed nausea. Use a 0.10 significance level to test the claim that more than 20% of users develop nausea. Identify the null and alternative hypotheses for this test. Choose the correct answer below. A. Ho: p=0.20 H₁ :p #0.20 B. Ho: p=0.20 H₁: p > 0.20 C. Ho: p=0.20 H₁: p0.20 H₁: p=0.20 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.)
