Question
In a test of the effectiveness of garic for lowering cholesterol, 49 subjects were treated with raw garlic. Cholesterol levels were measured before and ater the treatment. The changes (before minu after)
in their levels of LDI. cholesterol (in mgid.) have a mean of 0.8 and a standard deviation of 1.75. Use a0.10 signiicance level to test the ciaim that with garlic troatment, the mean change in LDL
cholesterol is greater than 0. What do the results suggest about the effectiveness of the gartic treatment? Assume that a simple random sample has been selected. identily the nul and aternative
hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.
