Question
(Round all intermediate calculations to at least 4 decimal places.) According to the World Health Organization, obesity has reached epidemic proportions globally. While obesity has generally been linked with chronic disease and disability, researchers argue that it may also affect wages. Body Mass ndex (BMI) is a widely used weight measure that also adjusts for height. A person is considered normal weight if BMl is between 18.5 to 25, overweight if BMl is between 25 to 30, and obese if BMI is over 30. The accompanying table shows data on the salary of 30 college-educated men with their respective BMI Salary (in $1,000s) BMI 34 26 26 35 34 42 37 35 46 46 20 20 26 28 20 35 26 45 25 32 46 31 54 37 42 38 45 38 41 39 50 41 38 29 30 31 19 30 26 28 28 20 26 28 21Explanation / Answer
I hope I have to solve for b-2 and b-3 only which are left blank to solve.
(b-2) The exponential model equation:
ln(salary) = 4.3327 - 0.0248 BMI
Putting BMI = 25 in the above equation gives, ln(salary) = 4.3327 - 0.0248 * 25
ln(salary) = 4.3327 - 0.62 = 3.7127
salary = e3.7127 = 40.948
(b-3) ln(salary) = 4.3327 - 0.0248 BMI
Putting BMI = 30 in the above equation gives, ln(salary) = 4.3327 - 0.0248 * 30
ln(salary) = 4.3327 - 0.744 = 3.5887
salary = e3.5887 = 36.173
