17) In an experiment, 16% of 734 subjects treated with viagra experienced headaches. In the same experiment, 4% of 725 subjects given a placebo experienced headaches. Use a .01 level of significance to test the claim that the proportion of headaches is greater for those treated with viagra.

A home improvement company is interested in improving customer satisfaction rate from the 58% currently claimed. The company sponsored a survey of 273 customers and found that 171 customers were satisfied. Determine whether sufficient evidence exists that the customer satisfaction rate is different than the claim by the company.

In a previous poll, 41% of adults with children under the age of 18 reported that their family ate dinner together seven nights a week. Suppose that, in a more recent poll, 461 of 1173 adults with children under the age of 18 reported that their family ate dinner together seven nights a week. Is there sufficient evidence that the proportion of families with children under the age of 18 who eat dinner together seven nights a week has decreased? Use the a = 0.05 significance level. Because npo (1-Po) = 10 and the sample size is V 5% of the population size, and the sample the requirements for testing the hypothesis satisfied. (Round to one decimal place as needed.) What are the null and alternative hypotheses? V versus H, Но (Type integers or decimals. Do not round.) Find the test statistic, zo- Zn = (Round to two decimal places as needed.) Find the P-value. P-value = (Round to three decimal places as needed.) Is there sufficient evidence that the proportion of families with children…

Consider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 6225 patients treated with this drug, 164 developed the adverse reaction of nausea. Use a 0.01 significance level to test the claim that 3% of users develop nausea. Does nausea appear to be a problematic adverse reaction? OC. Ho:p= 0.03 H4:p>0.03 O D. Ho: p#0.03 H:p=0.03 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is. (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. O A. Reject Hn. There is sufficient evidence to warrant rejection of the claim that 3% of users develop nausea. O B. Reject Ho. There is not sufficient evidence to warrant rejection of the claim that 3% of users develop nausea. OC. Fail to reject Ho. There is sufficient evidence to warrant rejection…
