Question
2) A dispenser fills mineral water bottles; the average amount of mineral water in each bottle is 32 ounces, with a standard deviation of 0.06 ounces. Assume the mean amount of mineral water is roughly normally distributed. To determine whether the machine is working properly, 36 filled bottles will be chosen at random and the mean amount will be calculated. Using a = 0.05, find the power of test if the true mean is 31.97.
