A bottle contasins a tabel stating that it contains pills with 500 mg of vitamin C, and another bottle contains a label stating that it contains pills with 325 mg of aspirin. When testing claims about the mean contents of the pills, which wouid have moserious implications rejection of the vitamin C olaim or rejection of the aspirin claim? Considering only a type l error and using the same sample size, is it wise to use the same significance level for hypothenis tests about the maan amount ofvitamin Cand the mean amount of aspirin?Rejection of the clam aboutclaim about the anpinn.V more senious because the wrongdosage could cause more serious adverse reanctions than a wrongdosage. It would be wise to use aV significance level for testing the

In this case, we need to fill the blanks with suitable answers.

The average retirement age in America is 66 years old. Do small business owners retire at an older average age? The data below shows the results of a survey of small business owners who have recently retired. Assume that the distribution of the population is normal. 63, 74, 59, 64, 74, 60, 71, 67, 65, 70, 63 What can be concluded at the the � = 0.05 level of significance level of significance? For this study, we should use The null and alternative hypotheses would be: �0: �1: The test statistic = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is � Based on this, we should the null hypothesis. Thus, the final conclusion is that ...

In a study of the accuracy of fast food drive-through orders, one restaurant had 31 orders that were not accurate among 355 orders observed. Use a 0.10 significance level to test the claim that the rate of inaccurate orders is equal to 10%. Does the accuracy rate appear to be acceptable? Question content area bottom Part 1 Identify the null and alternative hypotheses for this test. Choose the correct answer below. A. H0: p≠0.1 H1: p=0.1 B. H0: p=0.1 H1: p<0.1 C. H0: p=0.1 H1: p≠0.1 Your answer is correct. D. H0: p=0.1 H1: p>0.1 Part 2 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is negative 0.80−0.80.

We want to know if there is a difference between the mean list price of a three bedroom home, μ3, and the mean list price of a four bedroom home, μ4, H0:μ3=μ4 versus Ha:μ3≠μ4. Suppose we get a p-value of 0.1325, which is the proper conclusion of this test? a) We accept the null hypothesis at 5% significance. There is extremely strong evidence of a significance difference between the mean list price of three bedroom homes and the mean list price of four bedroom homes. b) We reject the null hypothesis at 5% significance. There is no evidence of a significance difference between the mean list price of three bedroom homes and the mean list price of four bedroom homes. c) We fail to reject the null hypothesis at 5% significance. There is no evidence of a significance difference between the mean list price of three bedroom homes and the mean list price of four bedroom homes. d) We reject the null hypothesis at 5% significance. There is extremely strong evidence of a significance difference…
