Serum cholesterol is an important risk factor for coronary
disease. We can show that serum cholesterol is approximately
standard deviation = 50 mg/dL.
*5.14 If the clinically desirable
< 200 mg/dL, what proportion of people have clinically
desirable levels of cholesterol?
*5.15 Some investigators believe that only cholesterol
levels over 250 mg/dL indicate a high-enough risk for heart
disease to warrant treatment. What proportion of the population does this group represent?
*5.16 What proportion of the general population has
borderline high-cholesterol levels—that is, > 200 but
< 250 mg/dL?
