The National Highway Traffic Safety Administration reported the percentage of traffic accidents occurring each day of the week. Assume that a sample of 420 accidents provided the following data. Sunday Monday Tuesday Wednesday Thursday Friday Saturday 66 51 53 47 54 69 80 (a) Conduct a hypothesis test to determine if the proportion of traffic accidents is the same for each day of the week. Use a 0.05 level of significance. State the null and alternative hypotheses. O Ho: Not all proportions are equal. Hạ: PSun = PMon = PTue = Pwed = PThu = PFri = Psat == O Ho: Psun * PMon + PTue + Pwed * PThu * PFri * PSat * G H: All proportions are equal. O Ho: Not all proportions are equal. 1 Ha: PSun * PMon * PTue * Pwed * PThu * PFri * Psat * 1 O Ho: Psun = PMon = PTue = Pwed = PThu = PFri = PSat = H: Not all proportions are equal. Find the value of the test statistic. (Round your answer to three decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value = State your conclusion. O Reject Ho. We conclude that the proportion of traffic accidents is the same for each day of the week. O Do not reject Hn. We conclude that the proportion of traffic accidents is not the same for each day of the week. O Do not reject Hn. We conclude that the proportion of traffic accidents is the same for each day of the week. O Reject Ho. We conclude that the proportion of traffic accidents is not the same for each day of the week.
