Question details

5. A persons Body-Mass Index (BMI) is calculated by dividing weight (in kilograms) by height2 (in meters). According to the book, The Changing Body, the BMI values of non-Hispanic adult males in the United States are approximately Normally distributed with mean (μ) = 26.5 and standard deviation (σ) = 4.0. Find the standardized scores associated with the thresholds between different categories. a. Underweight vs. Normal (BMI 18.5) b. Normal vs. Overweight (BMI 25) c. Overweight vs. Obese (BMI 30) 6. Combine the standardized scores you calculated in problem 5 and the Standard Normal Table to find the percentage of non-Hispanic adult American males in each of the four categories: % of non-Hispanic American adult males are underweight (BMI less than 18.5) % of non-Hispanic American adult males have normal weight (BMI between 18.5 and 25) % of non-Hispanic American adult males are overweight (BMI between 25 and 30). - % of non-Hispanic American adult males are obese (BMI greater than 30)7. Below is a drawing of a Standard Normal Distribution, a bell-curve density function. Vertical lines have been drawn for every half of a standard deviation away from the mean. IlIlustrate the calculations you performed in question 6 as follows: [a] draw a vertical line that divides underweight and normal weights (i.e., BMI 18.5), [b] draw a vertical line that divides normal weight and overweight (i.e., BMI 25), [c] draw a vertical line that divides overweight and obese (i.e., BMI 30). 19.1%)19.1% 15.0% 15.0% 9.2% 9.2% 0.1% 0.5% 4.4% 4.4% 0.5% 0.1% 7% 1.7%
