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 50 53 47 55 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. Hai Psun * PMon * PTue * Pwed * PThu * PFn * Psat * 7 O Ho: Not all proportions are equal Ha: Psun = PMon = PTue = Pwed = PThu = PFri = Psat = = O Ho: Psun * PMon * PTue * Pwed * PThu * PFri * Psat *= Ha: All proportions are equal. O Ho: Psun = PMon = PTue = Pwed = PThu = PFri = Psat = = He: 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 Do not reject Ho. We conclude that the proportion of traffic accidents is not the same for each day of the week. Reject Ho. We conclude that the proportion of traffic accidents is the same for each day of the week. Do not reject Ho- 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. (b) Compute the percentage of traffic accidents occurring on each day of the week. (Round your answers to two decimal places.) Sunday % Monday % Tuesday % Wednesday 1% Thursday 1% Friday 1% Saturday What day has the highest percentage of traffic accidents? O Sunday Monday Tuesday O Wednesday O Thursday
