The changes ​(before​-after) in their levels of LDL cholesterol​ (in mg/dL) have a mean of 3.5 and a standard deviation of 16.7.

What does the confidence interval suggest about the effectiveness of garlic in reducing LDL​ cholesterol? What is the confidence interval estimate of the population mean ​μ?
