A manufacturer claims that the mean amount of juice in its 16 ounce bottle is 16.1 ounces. A consumer advocacy group wants to perform a hypothesis test to determine whether the mean amount is actually less than this. Preliminary data analyses indicate that it is reasonable to apply a z test. Assume that population standard deviation is 0.8 ounces, n=60, and the significance level is 0.01. Find the probability of a type II error if in fact population mean is 15.8 ounces. 0.99 0.7157 0.2843
