n a test of the effectiveness of garlic for lowering​cholesterol, 8181 subjects were treated with raw garlic.Cholesterol levels were measured before and after the treatment.The changes​ (before minus​ after) in their levels of LDLcholesterol​ (in mg/dL) have a mean of 0.30.3 and a standarddeviation of 18.218.2. Use a 0.010.01 significance level to testthe claim that with garlic​ treatment, the mean change in LDLcholesterol is greater than 00. What do the results suggest aboutthe effectiveness of the garlic​ treatment? Assume that a simplerandom sample has been selected. Identify the null and alternative​hypotheses, test​ statistic, P-value, and state the finalconclusion that addresses the original claim. What are the null andalternative​ hypotheses? A. Upper H 0H0​: muμequals=00 ​mg/dL UpperH 1H1​: muμnot equals≠00 ​mg/dL B. Upper H 0H0​: muμequals=00​mg/dL Upper H 1H1​: muμgreater than>00 ​mg/dL C. Upper H 0H0​:muμgreater than>00 ​mg/dL Upper H 1H1​: muμless than<00​mg/dL D. Upper H 0H0​: muμequals=00 ​mg/dL Upper H 1H1​: muμlessthan<00 ​mg/dL Determine the test statistic. nothing ​(Round totwo decimal places as​ needed.)
