For a recent year, the following are the numbers of homicides that occurred each month in a city. Use a 0.05 significance level to test the claim that homicides in a city are equally likely for each of the 12 months. Is there sufficient evidence to support the police commissioner's claim that homicides occur more often in the summer when the weather is better? Full data set O Month Number Month Number Jan. 38 July Aug. Sep. Oc. Nov. 47 Feb. 31 50 March April May 46 50 39 43 45 38 June 48 Dec 38 Determine the null and alternative hypotheses. Calculate the test statistic, x. x2 = (Round to three decimal places as needed.) Calculate the P-value. P-value = (Round to four decimal places as needed.) %3D What is the conclusion for this hypothesis test? O A. Reject Ho. There is insufficient evidence to warrant rejection of the claim that homicides in a city are equally likely for each of the 12 months. O B. Reject Ho. There is sufficient evidence to warrant rejection of the claim that homicides in a city are equally likely for each of the 12 months. O C. Fail to reiect Ha.
