The manager of a grocery store wants to determine whether the amount of water contained in 1-gallon bottles purchased from a nationally known manufacturer actually averages 1 gallon. It is known from the specifications that the standard deviation of the amount of water is equal to .02 gallon. A random sample of 32 bottles is selected, and the mean amount of water per 1-gallon bottle is found to be .995 gallon. Calculate the p-value and test whether the specifications are being met at α = .001 using the p-value rule.
