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 55 66 49 53 W Ha: Psun PMon* PTue* Pwed* PThu * PFri * Psat # 47 (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. O Ho: Not all proportions are equal. Ha: Psun PMon=PTue Pwed PThu - PFri - Psat = - = O Ho: Psun PMon=PTue=Pwed=PThu = PFri = Psat H: Not all proportions are equal. 69 1 7 Find the p-value. (Round your answer to four decimal places.) p-value= O Ho: Psun PMon * PTue* Pwed* PThu * PFri * Psat * * H: All proportions are equal. Find the value of the test statistic. (Round your answer to three decimal places.) 81 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. O Reject Ho.
