A bottled water distributor wants to determine whether the mean amount of water contained in 1- gallon bottles purchased from a nationally known water bottling company is actually 1 gallon. You know from the water bottling company specifications that the standard deviation of the amount of water per bottle is 0.02 gallons. You select a random sample of 50 bottles, and the mean amount of water per 1-gallon bottle turns out to be 0.995 gallons in this sample.
