levels of all men age 20 to 34 years follows the Normal distribution with mean
per deciliter (mg/dl) and standard deviationo =41 mg/dl.

(a) Choose an SRS of 100 men from this population. What is the sampling dis-

mg/dl? This is the probability that x estimates u within +3 mg/dl.
(b) Choose an SRS of 1000 men from this population. Now what is the probability
that x falls within +3 mg/dl of u? The larger sample is much more likely to give
