A dentist wondered if his appointments were distributed evenly from Monday to Friday each week. He took a random sample of 500 appointments and recorded which day of the week they were booked for. His results are:

Day	Monday	Tuesday	Wednesday	Thursday	Friday
Appointment Frequency	98	112	124	94	72

The dentist would like to use these results to conduct a 22 goodness-of-fit test to determine if the distribution of appointments agrees with an even distribution using a 2.5% level of significance.
