Brewed decaffeinated coffee contains some caffeine. We want to estimate the amount of caffeine in 8 ounce cups of decaf coffee at local fast food restaurants. For this question, assume that the standard deviation in the amount of caffeine in 8 ounces of decaf coffee is not known and is estimated to be 2.3 mg using the sample standard deviation. This time we took a sample of n = 9 eight-ounce cups of coffee from fast food restaurants on Robert Street in West St. Paul. The sample mean amount of caffeine turned out to be 9 mg. Construct a 99% confidence interval estimate for the true mean amount of caffeine in eight-ounce cups of decaf coffee, using the new information described above. Type the formula for your confidence interval into the text box first and then type a second version where you fill in all of the numbers in your formula. You don't have to calculate the final numeric result.
