Question 1169396: In a test of the effectiveness of garlic for lowering​ cholesterol, 43 subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes ​(before​after) in their levels of LDL cholesterol​ (in mg/dL) have a mean of 5.3 and a standard deviation of 16.9. Construct a ​90% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment. What does the confidence interval suggest about the effectiveness of garlic in reducing LDL​ cholesterol?
I would like to get more of a step by step and how to find the certain points to solve the question.
