The standard deviation of math test scores at one high school is 16.1. A teacher claims that the standard deviation of the girls' test scores is smaller than 16.1. A random sample of 22 girls results in scores with a standard deviation of 13.3. Use a significance level of 0.01 to test the teacher's claim. Find the test statistic - chi square, the critical value -chi square and the p value.
