A quality control specialist for a restaurant chain takes a random sample of size 11 to check the amount of soda served in the 16 oz. serving size. The sample mean is 13.90 with a sample standard deviation of 1.53. Assume the underlying population is normally distributed. We wish to construct a 95% confidence interval for the true population mean for the amount of soda served.
