Agovernment sample survey plans to measure the ldl (bad) cholesterol level of an srs of men aged 20 to 34.
suppose that in fact the ldl cholesterol level of all men aged 20 to 34 follows the normal distribution with mean
? = 118
milligrams per deciliter (mg/dl) and standard deviation
? = 25 mg/dl.
use table a for the following questions, where necessary.
(a) choose an srs of 100 men from this population. what is the sampling distribution of x? (use the units of mg/dl.)
n(0.118, 0.025)
n(118, 2.5)
n(118, 0.25)
n(1.18, 0.25)
n(118, 25)
