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, y2. x2 = 27.315 (Round to three decimal places as needed.) Calculate the P-value. P-value = (Round to four decimal places as needed.)

Police Calls The police department in Madison, Connecticut, released the following numbers of calls for the different days of the week during a February that had 28 days: Monday (114); Tuesday (152); Wednesday (160); Thursday (164); Friday (179); Saturday (196); Sunday (130). Use a 0.01 significance level to test the claim that the different days of the week have the same frequencies of police calls. Is there anything notable about the observed frequencies?

Which of the following best describes the meaning of a p value for a chi squared score? a) A p value is another way to look at a chi squared score, so a low p value is essentially the same thing as a low chi squared score. b) A low p value means that the data is not likely to show any pattern or correlation. c)The higher the chi squared score, the lower the p value, because high chi squared scores mean the data looks like random data. d)A higher chi squared score means that the data was different from expected, and therefore unlikely to have occurred by chance.
Solve for the p-value.
