    Manufacturing and selling drugs that claim to reduce an individual's cholesterol level is big business.


    A company would like to market its drug to women if their cholesterol is in the top 15%. Assume the


    cholesterol levels of adult women can be described by a Normal model with a mean of 188 mg/dL


    and a standard deviation of 24. [5+5+5+5+5 points]


    (a) What percent of adult women has cholesterol levels over 200 mg/dL?


    (b) What is the 25th percentile?


    (c) What percent of adult women has cholesterol levels between 150 and 170 mg/dL?


    (d) I am about to test ve individuals, randomly selected from the population. What is the Prob-


    ability that at least one of them will have cholesterol levels between 150 and 170 mg/dL?


    (e) Above what value are the highest 15% of women's cholesterol levels?
