A random sample of 17 values was selected from a population, and the sample standard deviation was computed to be 150. Based on this sample result, compute a 90% confidence interval estimate for the true population standard deviation. State the UPPER bound of this confidence interval. (Hint: Use the formula for calculating a confidence interval estimate for a population variance. For this problem, the chi-squared critical value you should use is 5.8919. Also, don't forget, it is asking you for the confidence interval for the standard deviation. Chapter 11.1) (Round to two decimal places as needed.)
