Suppose a recent survey found that 74% of dog owners say their pet appears cheerful, while only 59% of cat owners say their pet appears cheerful. If one wants to perform a test to see if these two proportions are significantly different, what would the null and alternative hypotheses be?

In a clinical trial of a drug intended to help people stop smoking, 131 subjects were treated with the drug for 13 weeks, and 13 subjects experienced abdominal pain. If someone claims that more than 8% of the drug's users experience abdominal pain, that claim is supported with a hypothesis test conducted with a 0.05 significance level. Using 0.18 as an alternative value of p, the power of the test is 0.96. Interpret this value of the power of the test.

Burnout. According to a recent survey 45% of health care workers ages 18-29 reported feeling burnout from their jobs. Researchers believe that the level of burnout among older workers is even higher than that of younger workers. To test this belief they collected data from a random sample of 237 healthcare workers ages 50-64, and observed that 55% of healthcare workers in this age group reported feeling burnout from their jobs. Which of the following describes the null hypothesis for this study? 1). Null hypothesis: p=0.55 2) Null hypothesis: p=.45 3) Null hypothesis: p>0.55 4) Null hypothesis: p>0.45
Four drug companies are studying the effect of their new drugs. In its clinical trials, company A used a one tailed test with a significance level of .01; company B used a one tailed test with a significant level of 0.05; company C used a two tailed test with a significant level of 0.01 and company D used a two tailed test with a significant level of 0.05. Which of the following statement is correct? Company A is more likely to reject the null hypothesis (H0) than company B Company A is more likely to reject the null hypothesis (H0) than company C Company D is more likely to reject the null hypothesis (H0) than company B Company D is more likely to reject the null hypothesis (H0) than company C
A Gallup poll asked a sample of Canadian adults if they thought the law should allow doctors to end the life of a patient who is in great pain and near death if the patient makes a request in writing. The poll included 250 people in Quebec, 198 of whom agreed that doctor-assisted suicide should be allowed.(a) What is the margin of error of the large-sample 99.9% confidence interval for the proportion of all Quebec adults who would allow doctor-assisted suicide? MoE:(b) How large a sample is needed to get a±3 percentage point margin of error (this is very commonly used)? Use the previous sample as a pilot study to get p*.
