Suppose the distribution of serum cholesterol values in undergraduate men is approximately normally distributed with mean mu = 190 mg/dl and standard deviation sigma = 40 mg/dl. a) What is the probability of selecting someone at random from this population who has a cholesterol value that is less than 180? b) You take a simple random sample of n = 49 individuals from this population and calculate the mean cholesterol of the sample. Describe the sampling distribution of x-bar? c) Regarding the mean derived from a sample of n = 49, what is the probability of getting a sample mean that is less than 180?

Assume total cholesterol levels (TChol) are normally distributed with mean μ = 215 mg/dl and standard deviation σ = 30 mg/dl for the adult American population. That is, TChol ~ N(215, 302). Total cholesterol values of 240 mg/dl or greater are considered high; and levels in the range of 200 to 240 are called borderline high. a. What proportion of this population do we expect to find with high cholesterol? What proportion do we expect to find with borderline high...
