A soft drink machine is regulated so that the amount of drink dispensed is approximately normally distributed with a standard deviation equal to 1.5 deciliters. Find the 95% confidence interval for the mean of all soft drinks dispensed by this machine if a random sample of 36 drinks had an average content of 22.5 deciliters. What statistical table to be used? What is the tabular value? What is the computed lower confidence limit? What is the computed upper confidence limit?
