A quality control specialist for a restaurant chain takes a random sample of size 14 to check the amount of soda served in the 16 oz. serving size. The sample mean is 13.40 with a sample standard deviation of 1.59. Assume the underlying population is normally distributed.

Find the 95% confidence interval for the true population mean for the amount of soda served. (Round your answers to two decimal places.)

Answer #1

Solution:- Given that mean = 13.4, sd = 1.59, n = 14
df = n-1 = 14-1 = 13
