Kellogg's cereal company regularly tests its production line to ensure the accuracy of the loading mechanisms.  From a population of cereal boxes marked "12 ounces," a random sample of [n=16 boxes] is selected and the contents of each box is weighed.  The sample revealed a sample mean of [x=11.7 ounces], with a standard deviation [s=0.8 ounces].  Test to see if the population mean [Mu] is at least 12 ounces.  Use a 0.05 level of significance.
