Extracted text: 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? Day Sun Mon Tues Wed Thurs Fri Sat Frequency 157 200 220 244 176 209 231 Determine the null and alternative hypotheses. Ho: Police calls occur with the same frequency on the different days of the week. H,: At least one day has a different frequency of calls than the other days. Calculate the test statistic, x2. x2 = 27.315 (Round to three decimal places as needed.) %D Calculate the P-value. P-value = (Round to four decimal places as needed.)
