Q: From a population of cereal boxes marked "12 ounces," a sample of 16 boxes is selected and the contents of each box weighed. The sample revealed a mean of 11.7 ounces with a standard deviation of 0.8. Test to see if the mean of the population is at least 12 ounces. Use a 0.05 level of significance. (may use traditional or p-value method)
