A company was developing a new vitamin for those at risk from ailments associated with low calcium levels. In order to test the effectiveness of three new formulations a group of test subjects had their calcium levels tested before and after taking one of the three vitamins. The data are stored in vitamin .txt.

(a) Suggest a way to measure the effectiveness of treatment, and calculate this measure for each subject in the study.

(b) For each vitamin group construct a histogram for your measurement.

(d) Suggest another way the scientists could have tested the vitamin for mulations, especially if the number of test subjects was limited.
