Suppose that a random sample of 41 bottles of a particular brand of cough syrup is selected and the alcohol content of each bottle is determined. Let μ denote the average alcohol content for the population of all bottles of the brand under study. The resulting 95% confidence interval is (6, 10). What is the sample standard deviation, used to calculate the above interval
