Question: Suppose the object of a study is to determine the differences in effectiveness of Pravastatin and Lovastatin in reducing cholesterol levels of patients with a cardiovascular incident(s) and high lipid levels. Using the results below:

Table. Two Sample T Test for Cholesterol Reduction = TRMTGP

========================================================== TRTGP Mean N S.D. S.E. Variance T-Val. DF P-Val.

========================================================== 1 28.10 10 3.782 1.83 Equal 2.01 18 .0426

2 22.20 10 4.979 2.21 Unequal 1.99 17.4 .0502

F-Val. Num DF Den DF P-Val.

Test; equality of variances: 1.46 9 9 .4945

========================================================== TRMTGP denotes the two types of drugs; TRMTGP=1 for Pravastatin and TRMTGP=2 for Lovastatin.
