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 Frequency
Sun 154
Mon 205
Tues 227
Wed 249
Thurs 179
Fri 212
Sat 230
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.
