question 100

Multiple Choice

A cholesterol test was given to 10 heart patients with high cholesterol levels. The same 10 heart patients are then given a new cholesterol-reducing drug for six months. Before the patients begin taking the drug, they are told to maintain their current diets and eating habits so that the effect of the drug can be more effectively determined. After taking the drug for six months, the same patients are given a cholesterol test again. The pharmaceutical company that manufactures the drug wants to determine if the drug is helpful in reducing cholesterol levels. The cholesterol level readings are not normally distributed. State the alternative hypothesis for this problem.

• B) The probability distribution of cholesterol readings at the end of six months has shifted to the left of the probability distribution of cholesterol readings at the beginning of the trials.
• C) The probability distribution of cholesterol readings at the end of six months has shifted to the right of the probability distribution of cholesterol readings at the beginning of the trials.
• D) The probability distribution of cholesterol readings of patients at the end of six months has shifted to the right or left of the probability distribution of cholesterol readings at the beginning of the trials.
