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 cholesterol levels before and after taking the drug is given below.Distribution of cholesterol level is not normally distributed.At $\alpha$ = .05,test to determine if the drug is helpful in reducing cholesterol levels.
A)Reject the null hypothesis
B)Fail to reject the null hypothesis

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 cholesterol levels before and after taking the drug is given below.Distribution of cholesterol level is not normally distributed.At $\alpha$ = .05,test to determine if the drug is helpful in reducing cholesterol levels. 
A)Reject the null hypothesis 
B)Fail to reject the null hypothesis

Reject H₀H₀: The probability distribution of cholesterol readings of patients before and after taking the drug for six months is identical.H_A: The probability distribution of cholesterol readings of patients before taking the drug has shifted to the right of the probability distribution of cholesterol readings of patients after taking the drug.T_- = 1.5 + 1.5 + 8 = 1111 = 11,therefore we reject H₀ and conclude that the drug appears to be effective in reducing cholesterol levels.
