Use this table to answer the following questions based on your individual data. Compute probabilities based on the normal distribution. For each portion write a 1-sentence explanation as to how Excel was used to assist you in your computations. Find the percent of smokers expected to have a BMI of greater than 25 (overweight). Find the percent of nonsmokers expected to have a BMI of less than 18.5 (underweight). A normal BMI range is between 18.5 and 24.9. What percentage of smokers are expected to be within this range? What percentage of nonsmokers are expected to be within this range? A researcher is interested in which BMI represents the 90th percentile (where 90% are at this BMI level or lower). What BMI score represents the 90th percentile cut-off rate?
