We found xo.025 - 23.337 and xo.975 - 4.404. Recall the sample standard deviation s = 12.95, and sample size n - 13. Substitute these values to first find the lower bound for the confidence interval of the population variance, rounding the result to three decimal places. (n – 1)s2 xa/2 (13 - 1)12.952 lower bound - Now substitute these values to find the upper bound for the confidence interval of the population variance, rounding the result to three decimal places. (n – 1)s2 upper bound - X1- a/2 (13 – 1)12.952 Therefore, a 95% confidence interval for the population variance for the underpricing-overpricing indicator is to
