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  adult is 120-240 mg/dl. The Food and Nutrition  Institute of the Philippines found that the total  cholesterol level for the Filipino adults has a  mean of 159.2 mg/dl and 84.1% of adults have  a cholesterol level below 200 mg/dl. Suppose  that the total cholesterol level is normally  distributed. 1. Determine the standard deviation of this  distribution 2.What are the quartiles of this distribution? 3.What is the value of the cholesterol level that  exc
