hypothesis homework

A sample of 9 days over the past six months showed that a clinic treated the following numbers of patients: 24, 26, 21, 17, 16, 23, 27, 18, and 25. If the number of patients seen per day is normally distributed, would an analysis of these sample data provide evidence that the variance in the number of patients seen per day is less than 10? Use a = .025 level of significance. What is your conclusion using p-value and critical value approaches. Is the conclusion different in both the cases?
