Suppose 247 subjects are treated with a drug that is used to treat pain and 50 of them developed nausea. Use a 0.01 significance level to test the claim that more than 20% of users develop nausea. Identify the null and alternative hypotheses for this test, the test statistic for the hypothesis test, and p value for this hypothesis test & the conclusion?
Researchers conducted a study to assess the effect of an education campaign in increasing knowledge of Treatment as Prevention as a method of preventing transmission of HIV. Each participant's knowledge was assessed before and after a brief education campaign. Knowledge was assessed using a seven-point scale where 1 represents low knowledge and 7 represents high knowledge State the null hypothesis and alternative hypothesis for this study. b) What test is appropriate to test your null hypothesis? Why is this test appropriate? Provide supporting figures and/or statistics to justify your decision.
A study involved identical twins where one of the twins smoked and the other twin did not smoke. Researchers determined whether the twins developed heart disease. The data are below. Is there a relationship between smoking and heart disease? Was one of the twins more likely to develop heart disease? Use a 5% level of significance. 1) the appropriate null and alternative hypotheses; 2) the appropriate test; 3) the decision rule; 4) the calculation of the test statistic; and 5) your conclusion including a comparison to alpha or the critical value.

Past studies have indicated that the percentage of smokers was estimated to be about 34%. Given the new smoking cessation programs that have been implemented, you now believe that the percentage of smokers has reduced. You randomly surveyed 1708 people and found that 544 smoke. Use a 0.05 significance level to test the claim that the percentage of smokers has reduced.a) Identify the null and alternative hypotheses?H0H0: H1H1: b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? left-tailed right-tailed two-tailed c) Identify the appropriate significance level.d) Calculate your test statistic (Use ˆpp^ rounded to 4 decimal places). Write the result below, and round your test statistic to 4 decimal places.e) Calculate your p-value. Write the result below, rounded to four decimal places.f) Do you reject the null hypothesis? We reject the null hypothesis, since the p-value is less than the significance level. We reject the…
According to areport on consumer fraud and identity theft, 22% of all complaints during one year were for identity theft. In that year, Michigan had 322 complaints of identity theft out of 1457 consumer complaints. Does this data provide enough evidence to show that Michigan had a lower proportion of identity theft than 22%? State the Type I and Type II errors in this case. State the Type I error. O Concluding that the proportion of complaints from identity theft in Michigan is 22%, when it is less than 22%. Concluding that the proportion of complaints from identity theft in Michigan is 22%, when it is higher than 22%. O Concluding that the proportion of complaints from identity theft in Michigan is less than 22%, when it is 22%. O Concluding that the proportion of complaints from identity theft in Michigan is higher than 22%, when it is 22%. State the Type II error.
