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. (There is an error in this design because there are different number of occurrences for some days in a month, but just do this problem for the practice) Day Frequency Sun 153 Mon 208 Tues 221 Wed 245 Thurs 177 Fri 208 Sat 237 The null and alternative hypotheses are shown below. H0: Police calls occur with the same frequency on the different days of the week H1: At least one day has a different frequency of calls than the other days. a) Find the test statistic (Round to three decimal places as needed) b) Find p-value (Round to three decimal places as needed) c) Draw the conclusion. Please check the appropriate tutorial in the announcement.
