A quаlity cоntrоl engineer аt а pharmaceutical cоmpany is analyzing the weight variations of tablets produced by a new manufacturing process. A random sample of 25 tablets is selected, and their weights (in milligrams) are measured. The sample has a standard deviation of 0.42 mg. Construct a 95% confidence interval for the population variance of the weights of all tablets produced by this manufacturing process. Determine and interpret the 95% confidence interval for the population standard deviation.
