In a test of the effectiveness of garlic for lowering cholesterol, 36 subjects were treated with raw garlic. Cholesterol levels were measured before and after the treatment. The changes (before minus after) in their levels of LDL cholesterol (in mg/dL) have a mean of 0.3 and a standard deviation of 1.68. Use a 0.10 significance level to test the claim that with garlic treatment, the mean change in LDL cholesterol is greater than 0. What do the results suggest about the effectiveness of the garlic treatment? Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.

Part B: Identify the test statistic___ (Round your answer to two decimals as needed.)

Part C: Identify the P-value___ (Round your answer to three decimals as needed.)

In a test of the effectiveness of garlic for lowering cholesterol, 36 subjects were treated with raw garlic. Cholesterol levels were measured before and after the treatment. The changes (before minus after) in their levels of LDL
cholesterol (in mg/dL) have a mean of 0.3 and a standard deviation of 1.68. Use a 0.10 significance level to test the claim that with garlic treatment, the mean change in LDL cholesterol is greater than 0. What do the results
suggest about the effectiveness of the garlic treatment? Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses
the original claim.
What are the null and alternative hypotheses?
O A. Ho: µ>0 mg/dL
O B. Ho: µ =0 mg/dL
H1: µ<0 mg/dL
H1: µ #0 mg/dL
O C. Ho μ=0 mg dL
H1: µ<0 mg/dL
O D. Ho: H=0 mg/dL
H1: µ>0 mg/dL
