5. The baseline characteristics of different treatment groups are often included in journal articles. In one study, 49 subjects treated with raw garlic had LDL cholesterol measurements with a mean of 151 and a standard deviation of 15, while 48 subjects given placebos had LDL cholesterol measurements with a mean of 149 and a standard deviation of 14 (based on data from "Effect of Raw Garlic vs Commercial Garlic Supplements on Plasma Lipid Concentrations in Adults with Moderate Hypercholesterolemia," by Gardner et al., Archives of Internal Medicine, Vol. 167). Use a 0.05 significance level to test the claim that there is no difference between the mean LDL cholesterol levels of subjects treated with raw garlic and subjects given placebos. 1) Null Hypothesis, Ho: (2) Alternative Hypothesis, H1: (2) Test Statistic: (2) P-value: (1) Reject or fail to reject the null hypothesis? (2) Final conclusion that addresses the original claim. Model your answer on the wording found in Hypothesis Test: Wording of Final Conclusion. 5.
