An almond milk distributor wants to determine whether the mean amount of almond milk contained in a 1 gallon bottle purchased from a store-brand competitor is actually 1 gallon. You know that the population standard deviation for almond milk gallons is .07. You select a random sample of 24 bottles with a mean amount of almond milk per 1 gallon as 0.966 gallon. Evaluate that there is evidence that the mean is different from 1 gallon, using an alpha level of 0.05.?
