A manufacturer claims that the mean amount of juice in its 16 ounce bottles 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. They collect a simple random sample of 50 bottles and obtain a sample mean of 16.07 ounces and a sample standard deviation of 0.10 ounces. At a 0.01 level of significance, test the claim that the mean amount of juice in a bottle is less than 16.1 ounces.
