Scenario

The recommended number of calories for a young, active, female adult to consume in a day is 2,200 calories. Suppose you're a nutrition consultant for the female sports team at College Great. You would like to know whether the average amount of calories consumed per day, on average, for the female, varsity sports players at your college is equal to the recommended amount, 2,200 calories.

Now suppose others at the college get interested in this study, and they want to know if the female varsity sports players consume more calories than female students that do not play varsity sports.
