    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...
