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

0.010.01 how to solve the test statistic and p value on calculator?

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?

FrequencyFrequency	160160	200200	225225	241241	177177	214214	234234

Determine the null and alternative hypotheses.

Upper H 0H0​:

Police calls occur with the same frequency on the different days of the week.

Upper H 1H1​:

At least one day has a different frequency of calls than the other days.

Calculate the test​ statistic,

​(Round to three decimal places as​ needed.)

Calculate the​ P-value.

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.

Your answer is correct.

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.
