Question
A police department released the numbers of calls for the different days of the week during the month of October, as shown in the table to the right. Use a 0.01 significance level to test the daim that the different days of the week have the same trequencies of
police calls. What is the fundamental error with this analysis?

Determine the null and altemative hypotheses.
Ho
Calculate the test statistic, y
x2 =(Round to three decimal places as needed.)
Calculate the P-value.
P-value = (Round to four decimal places as needed.)
What is the conclusion for this hypothesis test?
O A. Fail to reject H. There is sufficient evidence to warrant rejection of the claim that the different days of the week have the same frequencies of police calls.
O B. Reject H. There is sufficient evidence to warrant rejection of the claim that the different days of the week have the same frequencies of police calls.
O C. Fail to reject H,. There is insufficient evidence to warrant rejection of the claim that the different days of the week have the same frequencies of police calls
O D. Reject Hn. There is insufficient evidence to warrant rejection of the claim that the different days of the week have the same frequencies of police calls.
