In a test of the effectiveness of garlic for lowering​ cholesterol, 49 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 0.8 and a standard deviation of 2.32. Use a 0.05 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. A. H0​: μ=0 ​mg/dL
H1​: μ>0 ​mg/dL
B. H0​: μ=0 ​mg/dL
H1​: μ≠0 ​mg/dL
C. H0​: μ=0 ​mg/dL
H1​: μ<0 ​mg/dL
D. H0​: μ>0 ​mg/dL
H1​: μ<0 ​mg/dL

(I also need the test statistic and p-value) thank you in advance :)
