The caffeine content (in mg) was examined for a random sample of 50 cups of black coffee dispensed by a new machine. The mean and the standard deviation were 110 mg and 7.1 mg respectively. Use the data to construct a 98% confidence interval for the mean caffeine content for cups dispensed by the machine. Interpret the interval!
Answers: 1
= 7.1
= 110
1 - confidence interval = 1 - .98 = .02
= 2.33 
= 112.34
= 107.66
