According to a study, a cup of coffee contains an average of 116 milligrams (mg) of caffeine, with the amount per cup ranging from 64 to 192 mg Suppose you want to repeat the experiment in order to obtain an estimate of the mean caffeine content in a cup of coffee correct to within 6 mg with 95% confidence. How many cups of coffee would have to be included in your sample? The experiment must sample cups of coffee in...
