MY NOTES ASK YOUR TEACHER PRACTICE ANO DETAILS You may need to use the appropriate technology to answer this question. 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. Ha: Psun * PMon * PTue * PWed # PThu * PFri * Psat * O Ho: Not all proportions are equal. Hai Psun = PMon = PTue = PWed = PThu = PFri = Psat = O Ho: Psun * PMon * PTue * Pwed * PThu * PFri * Psat * H. : All proportions are equal. O Ho: Psun = PMon = PTue = Pwed = PThu = PFri = Psat = 7 H : 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 H. We conclude that the
