(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 Hn: Not all proportions are equal.
H: PSun * PMon *+ PTue * Pwed * PThu * Pei * Psat *
Ho: Psun * PMon * PTue * Pwed * PThụ * Peri * Psat *
H: All proportions are equal.
O Hn: Not all proportions are equal.
H: Psun = PMon = PTue = Pwed = PThụ = Peri = PSat ==
1
O Ho: Psun - PMon = PTue = Pwed = PThu = PFri = PSat ==
%3!
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 Hn. We conclude that the proportion of traffic accidents is not the same for each day of the week.
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.
(b) Compute the percentage of traffic accidents occurring on each day of the week. (Round your answers to two decimal places.)
