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 95 114 125 97 69 The dentist would like to use these results to conduct a χ 2 goodness-of-fit test to determine if the distribution of appointments agrees with an even distribution using a 0.5% level of significance.
