MATH 133 Unit 3 - DB - BMI - A+ Guaranteed




Question;MATH 133 Unit 3 - DB - BMI - A+ Guaranteed;Body Mass Index;The United States is becoming more;health conscious, and as a result, the problem of obesity has gotten more;attention. The Body Mass Index (BMI), relates a person?s height and weight, and;is often used to determine if someone is overweight. The table below tells the;weight status for a given BMI.;BMI;Weight;Status;Below;18.5;Underweight;18.5;- 24.9;Normal;24.9;- 29.9;Overweight;29.9;and above;Obese;The BMI is calculated using the;formula;BMI = 703*w / h2 where;w is the weight in pounds and h is the height in inches.;1.;Using the Internet, AIU?s library, or;another research source, find the weight of your favorite celebrity. This could;be a movie or television personality, athlete, or a politician. You may also;use yourself.;2. Using the weight you found in;Question 1, determine the height the celebrity (or yourself) would need to be;to fall into each of the four weight status categories listed in the table. In;other words, select a BMI less than 18.5 (any value), and find h. Then, repeat;using a new BMI in each range. Show all of your work for each of these;calculations.;2.;Using your chosen BMI values and the;corresponding four heights calculated in Question 2, and using Excel or another;graphing utility, draw the graph of your celebrity?s heights as a function of;the BMI. (The function being graphed is h = sqrt(703 ? w / BMI), so BMI is the;independent [or horizontal] variable.) Insert the graph into a Word document;and attach that Word document to the DB thread, or paste your graph into the DB;thread.;Using the Internet or other library;resource, find the actual height of your celebrity;Using the height found in Question 4;calculate the person?s actual weight status (underweight, normal, overweight;or obese) using the original BMI formula above;6. What would be the height;range (minimum and maximum heights) for your celebrity to be in the normal;weight status? In other words, based on your celebrity?s weight, what would be;the heights of the celebrity at BMIs of 18.5 and 24.9? (Show these;calculations.);7. Based on the celebrity?s;appearance, would you consider him or her to actually be in the weight status;that this formula says based on his or her actual height and weight and;considering his or her other physical characteristics? Why or why not? Think;about why there may be differences in your calculations and the actual figures.;8. The BMI formula was created;by a Belgian statistician (not a physician), Lambert Adolphe Quetelet, in about;1832. Quetelet was trying to determine the ?average? person?s weight relative;to his or her height. His ?Quetelet index? (later known as the BMI) was;developed using height and weight data of Europeans in the early 1800s. Do you;think that BMI is a fair indication of a person?s weight classification today?;Why or why not?;9. According to data collected;by the Centers for Disease Control (CDC) National Health and Nutrition Examination;Survey III, the following quadratic functions approximately represent the;median BMI values for men and women in the United States, where x is their age;(Halls, 2008, Halls, 2008);10. For your celebrity?s age;calculate the median BMI from the appropriate quadratic function above. Is your;celebrity?s actual BMI over or under this calculated median value? (Show all of;your work.);11. After studying BMI, why do;you think that BMI is so widely used by the federal government, health industry;professionals, and insurance companies as a measure of a person?s overall;health?;12. Summarize your findings in;writing using proper style and grammar.;13. Which intellipath Learning;Nodes helped you with this assignment?
