Find confidence interval for mean of all drinks dispensed

Reference no: EM13119200

A softdrink machine is regulated so that the amount of drink dispensed is approximately normally distributed with a standard deviation equal to 0.15 deciliter. Find a 95% confidence interval for the mean of all drinks dispensed by this machine if a random sample of 36 drinks has an average content of 2.25 deciliters.
