Many people suffer from high levels of cholesterol, which can lead to heart attacks.
For those with very high levels (over 280), doctors prescribe drugs to reduce
cholesterol levels. A pharmaceutical company has recently developed four such drugs.
To determine whether any differences exits in their benefits, an experiment was
organized. The company selected 25 groups of four men, each of whom had
cholesterol level in excess of 280. In each group, the men were matched according to
age and cholesterol was recorded.
