Question:

NHES. A National Center for Health Statistics survey suggested that, in the late 1970s, the mean serum cholesterol level in men was μ =

210 mg/dL with standard deviation σ = 90 mg/dL. You sample n = 36 men from the population and are willing to assume that the sampling distribution of is approximately Normal. What is the probability of finding an of 240 or greater in your sample? (Suggestions:

Calculate the standard error of the mean. Then sketch the sampling distribution of showing the location of = 240 on the horizontal axis. Shade the region corresponding to the area under the curve beyond 240.)
