A Local Grocery Store Wants to Estimate the Mean Daily

Short Answer

A local grocery store wants to estimate the mean daily number of gallons of milk sold to customers. Assume the number of gallons sold follows the normal distribution with a population standard deviation of 5.10 gallons. A random sample of 60 days shows that the mean daily number of gallons sold is 10.00. Compute a 99 percent confidence interval for the population mean.
