In a test of the effectiveness of garlic for lowering cholesterol, 81 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 0.6 and a standard deviation of 1.93. 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 garli 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 u= 0 mg/dL H, u<0 mg/dL O B. Ho µ= 0 mg/dL H,. µ# 0 mg/dL C. Ho H=0 mg/dL H, p>0 mg/dL OD Ho p>0 mg/dL H, µ<0 mg/dL Determine the test statistic. (Round to two decimal places as needed.)

Can you help me find the test statistics and the p-value
![In a test of the effectiveness of garlic for lowering cholesterol, 81 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 mq/dL) have a mean of 0.6 and a standard deviation of 1.93. 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.
What are the null and alternative hypotheses?
O A. Ho µ= 0 mg/dL
H u<0 mg/dL
O B. Ho: µ= 0 mg/dL
H, p 0 mg/dL
C. Ho p= 0 mg/dL
OD Ho µ>0 mg/dL
H, u<0 mg/dL
H p>0 mg/dL
Determine the test statistic.
