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 is 0.011 gallon. You select a random sample of 45 bottles, and the mean amount of water per 1-gallon bottle is 0.995 gallon. Complete parts (a) through (e) below. a. Is there evidence that the mean amount is different from 1.0 gallon? (Use a = 0.05.) Let u be the population mean. Determine the null hypothesis, Ho, and the alternative hypothesis, H1. Ho: H 1.0 Hy: H 1.0
