Extracted text: The level of cholesterol in the blood for all men aged 20 to 34 follows a Normal distribution with mean uM = 188 milligrams per deciliter (mg/dl) and standard deviation oM = 41 mg/dl. For 14-year-old boys, blood cholesterol levels follow a Normal distribution with mean wg = 170 mg/dl and standard deviation og = 30 mg/dl. Suppose we select independent SRSS of 25 men aged 20 to 34 and 36 boys aged 14 and calculate the sample mean cholesterol levels iM and What is the mean of the sampling distribution of XM - g?
