College freshmen are weighed before and after they take a health/fitness course. The program’s developer wants to determine if there is a weight change in those students who complete the course. Because many freshmen are still growing, and because they are experiencing dorm food with unlimited seconds for the first time, it is not clear whether their weight will increase or decrease by at the end of the program. Let D equal the weight change, post weight Y minus pre-weight X, the observation D (in kilograms) for 16 randomly chosen women taking the course were: -3.2 0.2 2.0 1.3 0.9 3.7 0.3 -0.8 0.2 - 0.5 1.4 -2.2 -0.1 0.6 0.2 -0.1 What conclusion can you draw out of the given data at 0.01 level? State your hypothesis and show your solution and state your final conclusion.
