.2.14 Question Help In a test of the effectiveness of garlic for lowering cholesterol, 49 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 4.7 and a standard deviation of 16.1. Construct a 90% confidence interval estimate of the mean not change in LDL cholesterol after the garlic treatment. What does the confidence interval suggest about the effectiveness of garlic in reducing LDL cholesterol?

Question Help Assume that all grade-point averages are to be standardized on a scale between 0 and 5. How many grade-point averages must be obtained so that the sample man is within 0.009 of the population mean? Assum that a 95% confidence wivel is desired. If using the range rule of thumb, o can be estimated as range 5-0 4 125. Does the sample size sem practical? The required sample size is Round up to the nearest whole number as needed) 4
