Extracted text: 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 H,: Not all proportions are equal. H: Psun = PMon = PTue = Pwed = PThu = PFri = PSat = O Ho: PSun * PMon * PTue * Pwed * PThu * Peri * Psat H: All proportions are equal. O Ho: PSun = PMon = PTue = Pwed = PThu = PFri = PSat == %3D %3! H: Not all proportions are equal. H: Not all proportions are equal. H: Psun * PMoon * PTue Pwed + PThu * Per Psat Find the value of the test statistic. (Round your answer to three decimal places.) 14.334 Find the p-value. (Round your answer to four decimal places.) p-value = 14.334 State your conclusion. O Reject H. We conclude that the proportion of traffic accidents is not the same for each day of the week. O Do not reject H.. We conclude that the proportion of traffic accidents is the same for each day of the week. O Reject H,. We conclude that the proportion of traffic accidents is the same for each day of the week. O Do not reject H. 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 % Thursday % Friday % Saturday %
