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 52 80 66 50 48 Ho: Psun* PMon * PTue * Pwed * PThu * PFri * Psat */ / # Ha: All proportions are equal. O Ho: Not all proportions are equal. Ha: Psun* PMon * PTue * Pwed* PThu * PFri * Psat * =-=- (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. Ho: Psun - PMon=PTue Pwed=PThu=PFri Psat = = Ha: Not all proportions are equal. = 55 O Ho: Not all proportions are equal. H₂: Psun = PMon =PTue = Pwed=PThu = PFri = Psat == / X 69 Find the p-value. (Round your answer to four decimal places.) p-value= .0239 x Find the value of the test statistic. (Round your answer to three decimal places.) 14.567 X
