=+17. When the population distribution is normal and n is large, the statistic s has approximately a normal distribution with s , s y12n. Use this fact to develop a large-sample two-sided confidence interval formula for . Then calculate a 95% confidence interval for the true standard deviation of the fracture strength distribution based on the data given in Exercise 16 (the cited paper gave compelling evidence in support of assuming normality).
