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...

Total Cholesterol According to the U.S. Center for Disease Control (CDC), the mean total cholesterol for men between the ages of 20 and 29 is 180 micrograms per decilitre with a standard deviation of 36.2. A healthy total cholesterol level is less than 200, 200–240 is borderline, and above 240 is dangerous. Assume that the distribution is approximately Normal. a. For a randomly selected man from this group, what is the probability that his total cholesterol level is 200 or...

A particular population, for which the frequency curve is bell-shaped (normal), has a mean of μ=100 and a standard deviation of σ=18. For samples of size n=36 consider the sampling distribution of the sample mean ("xbar"). Note that {18\squareroot of 36) =3 and that 100±(1)(3)⟹97 to 103 100±(2)(3)⟹94 to 106 100±(3)(3)⟹91 to 109 According to the empirical rule, approximately _____ percent of samples of size 36 will produce a sample mean between 97 and 103.
