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? a. Calculate the test statistic, χ2. χ2= (Round to three decimal places as needed.) b. Calculate the P-value. P-value= (Round to four decimal places as needed.)
