a. What percent of adult women do you expect to have cholesterol levels over 200 mg/dL?

b. What percent of adult women do you expect to have cholesterol levels below 185 mg/dL?

c. What percent of adult women do you expect to have cholesterol levels between 150 and 170 mg/dL?

d. Below what value is the lowest 5% of women's cholesterol levels?

e. Estimate the interquartile range of the cholesterol levels.

f. Above what value are the highest 15% of women's cholesterol levels?

2. On a recent math test, the mean score was 75 and the standard deviation was 5. Mike made 93. SHOW ALL WORK IN EXCEL.

a. What is the 25th percentile for the math scores (remember, this is the same as Q1)?

b. What is the 75th percentile for the math scores (remember, this is the same as Q3)?

c. Find IQR , LB and UB.

d. Using the values, you found in parts (a) and (b) determine if Mike's score is an outlier
