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?

Determine the null and alternative hypotheses.
H0​:
 
At least two days have a different frequency of calls than the other days.
Police calls occur with all different frequencies on the different days of the week.
At least one day has a different frequency of calls than the other days.
Police calls occur with the same frequency on the different days of the week.
H1​:
 
At least two days have a different frequency of calls than the other days.
Police calls occur with all different frequencies on the different days of the week.
At least one day has a different frequency of calls than the other days.
Police calls occur with the same frequency on the different days of the week.
 
 

Calculate the test​ statistic, χ2.

Calculate the​ P-value

What is the conclusion for this hypothesis​ test?
 
a. H0. There is sufficient evidence to warrant rejection of the claim that the different days of the week have the same frequencies of police calls.
 
B. Reject H0. There is insufficient evidence to warrant rejection of the claim that the different days of the week have the same frequencies of police calls. Your answer is not correct.
 
C. Reject H0. There is sufficient evidence to warrant rejection of the claim that the different days of the week have the same frequencies of police calls. This is the correct answer.
 
D. Fail to reject H0. There is insufficient 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, three of the days of the week occur more often than the other days of the week.
This is the correct answer.
 
B.Because October has 31​ days, one of the days of the week occur more often than the other days of the week.
 
C.Because October has 31​ days, two of the days of the week occur more often than the other days of the week.
 
D.Because October has 31​ days, each day of the week occurs the same number of times as the other days of the week.
Your answer is not correct.
