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 claim that the different days of the week have the same
frequencies of police calls. What is the fundamental error with this analysis?

Determine the null and alternative hypotheses.
Ho:
H1:
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.)
What is the conclusion for this hypothesis test?
O A. Fail to reject Ho. 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 B. Reject Ho. There is sufficient evidence to warrant rejection of the claim that the different days of the week have the same frequencies of police calls.
C. Reject Ho: There is insufficient evidence to warrant rejection of the claim that the different days of the week have the same frequencies of police calls.
D. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that the different days of the week have the same frequencies of police calls.
What is the fundamental error with this analysis?
O A. Because October has 31 davs, two of the davs of the week occur more often than the other davs of the week.
