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

Days	Sun	Mon	Tues	Wed	Thurs	Fri	Sat
Frequency	157	205	228	246	179	214	230

Calculate the test​ statistic:

Calculate the​ P-value:

What is the conclusion for this hypothesis​ test?

A. Fail to reject Upper H 0. There is insufficient evidence to warrant rejection of the claim that the different days of the week have the same frequencies of police calls.

B. Reject Upper H 0. There is insufficient evidence to warrant rejection of the claim that the different days of the week have the same frequencies of police calls.

C. Reject Upper H 0. There is sufficient 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 Upper H 0. 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?

A. Because October has 31​ days, two of the days of the week occur more often than the other days of the week.

B. Because October has 31​ days, each day of the week occurs the same number of times as the other days of the week.

C. Because October has 31​ days, three of the days of the week occur more often than the other days of the week.
