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 53 48 80 66 50 O Ho: Psun #PMon * PTue *Pwed* PThu * PFri * Psat * = H: All proportions are equal. O Ho: Not all proportions are equal. H₂: Psun = PMon * PTue #Pwed* PThu * PFri * Psat OH: Not all proportions are equal. H₂: Psun (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. 55 PMon Tue Wed Thu Fri Sat 7 Ho: Psun = PMon =PTue = Pwed=PThu = PFri = Psat === H₂: Not all proportions are equal. 68 Find the p-value.
