in a test of the effectiveness of garlic for lowering cholesterol, 50 subjects were treated with garlic in a processed tablet form. cholesterol levels were measured before and after treatment. the changes (before - after) in their levels of LDL cholesterol have a mean of 3.7 and a standard deviation of 18.9. construct a 99% 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? what is the confidence interval estimate of the population mean? what does the confidence interval suggest about the effectiveness of the treatment? does the confidence interval contain 0? and what does it suggest?

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.

In a test of the effectiveness of garlic for lowering cholesterol, 50 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 3.4 and a standard deviation of 15.3. Construct a 95% 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? The confidence interval limits do not contain 0, suggesting that the garlic treatment did affect the LDL cholesterol levels. B. The confidence interval limits contain 0, suggesting that the garlic treatment did not affect the LDL cholesterol levels. C.
