Watch your cholesterol: A sample of 316 patients between the ages of 38 and 82 were given a combination of drugs ezetimibe and simvastatin. They achieved a mean reduction in total cholesterol of 0.92 millimole per liter. Assume the population standard deviation is o= 0.18. Part: 0 / 3 Part 1 of 3 (a) Construct a 99% confidence interval for the mean reduction in total cholesterol in patients who take this combination of drugs. Round the answer to at least two decimal places. A 99% confidence interval for the mean reduction in cholesterol is <μ< |· Espa

(b) Should this confidence interval be used to estimate the mean reduction in total cholesterol for patients over the age of 86? be used to estimate the mean reduction in total cholesterol The confidence interval should for patients over the age of 86. Part: 2/3 Part 3 of 3 X (c) Based on the confidence interval constructed in part (a), is it likely that the mean reduction in cholesterol level is less than 0.87? The mean reduction in total cholesterol (Choose one) likely to be less than 0.87. is is not Esp
