According to the Dental Association of Canada expect their members remain busy equally through out the year. If the variance of the number of patients seen per day is less than 10 then dentists are considered to be busy equally. A sample of 9 days over the past six months showed a dentist treated the following numbers of patients: 22, 25, 20, 18, 15, 22, 24, 19, and 26 per day. If the number of patients seen per day is normally distributed, test using sample data to examine if dentists in Canada remain busy equally throughout the year. (a) Formulate the null and alternative hypotheses (b) Calculate test statistic (c) Test the null hypothesis at = 0.1 (d) Draw your conclusion
