5. [-/1.12 Points] DETAILS PECKSTAT2 10.E.056.S. MY NOTES In a survey of 1,000 adult Americans, 46.1% indicated that they were somewhat Interested or very Interested in having web access in their cars. Suppose that the marketing manager of a car manufacturer claims that the 46.1% is based only on a sample and that 46.1% is close to half, so there is no reason to believe that the proportion of all adult Americans who want car web access is less than 0.50. Is the marketing manager correct in his claim? Provide statistical evidence to support your answer. For purposes of this exercise, assume that the sample can be considered representative of adult Americans. Test the relevant hypotheses using a = 0.05. LO USE SALT State the appropriate null and alternative hypotheses. O Ho: P = 0.50 versus Ha: p # 0.50 O Ho: P 0.50 O Ho: P = 0.50 versus Ha: p 0.50 Find the test statistic and P-value. (Use a table or SALT. Round your test statistic to two decimal places and your P-value to four decimal places.) P-value = State the conclusion in the problem context. Reject Ho. We have convincing evidence that the proportion of all adult Americans who want car web access is less than 0.50. The marketing manager is not correct in his claim. Fail to reject Ho. We do not have convincing evidence that the proportion of all adult Americans who want car web access is less than 0.50. The marketing manager is correct in his claim. Fail to reject Ho. We have convincing evidence that the proportion of all adult Americans who want car web access is less than 0.50. The marketing manager is not correct in his claim. Reject Ho. We do not have convincing evidence that the proportion of all adult Americans who want car web access is less than 0.50. The marketing manager is correct in his claim
