her's the original question: 8.9 A bottled water distributor wants to estimate the amount of water contained in 1-gallon bottles purchased from a nationally known water bottling company. The water bottling company's specifications state that the standard deviation of the amount of water is equal to 0.02 gallon. A random sample of 50 bottles is selected, and the sample mean amount of water per 1-gallon bottle is 0.993 gallon. A. Construct a 99% confidence interval estimate for the population mean amount of water included in a 1-gallon bottle. Answer: We are 99% confident that the true mean amount of water in a 1-gallon bottle is between 0.986 gallons and 1.000 gallons. B.On the basis of these results, do you think that the distributor has a right to complain to the water bottling company about the amount of water that the bottles contain? Why? The distributor has grounds to complain to the water bottling company because the 99% confidence interval for the mean amount of water in the bottles (0.986 to 1.000 gallons) suggests that, on average, the bottles may contain less than the expected 1 gallon
