Cholesterol is a fatty substance that is an important part of the outer lining (membrane) of cells in the body of animals. Its normal range for an adult is 120–240 mg/dl. The Food and Nutrition Institute of the Philippines found that the total cholesterol level for Filipino adults has a mean of 159.2 mg/dl and 83.89% of adults have a cholesterol level below 200 mg/dl. a. Determine the standard deviation of this distribution. Ans = Blank 1 mg/dl b. What is the value of the cholesterol level that exceeds 99% of the population? Ans = Blank 2 mg/dl
