Suppose that the blood cholesterol levels of all men aged 20 to 34 years follows the Normal distribution with mean
M = 188 milligrams per deciliter (m(g)/(d)l) and standard deviation o = 41 m(g)/(d)l.
(a) Choose an SRS of 100 men from this population. What is the sampling distribution of x?
The sampling distribution of x is
* N (18.8 m(g)/(d)l, 4.1 m(g)/(d)l).
* N (18.8 m(g)/(d)l, 41 m(g)/(d)i).
N (188 m(g)/(d)i, 4.1 m(g)/(d)1).
N (188 m(g)/(d)l, 41 m(g)/(d)l).
