Question
Choose the correct answer below.
A. For a person with a certain height and age, if their body fat increased by 1%, their total body weight is predicted to increase by 1.3643 pounds.
B. As body fat increases by 1%, total body weight is predicted to increase by 1.3643 pounds.
C. As body fat increases by 1%, total body weight is predicted to increase by 1.3643 pounds after accounting for the effects of height and age.
D. As total body weight increases by 1 pound, body fat is predicted to increase by 1.3643% holding height and age constant.
E. For a person with a certain height and age, if their body fat increased by 1.3643%, their total body weight is predicted to increase by 1 pound.

Here from the table of coefficients we see that the coefficient of the independent variable BF% is 1.3643 which basically means that for a person who has a certain height and age an increase in a unit percentage of the body fat, the total body weight is predicted to increase by 1.3643 pounds. Note that here we have to keep in mind that the rest of the independent variables have to be unchanged to define the effect of thie individual coefficient of the variable BF%.
Therefore A is the correct answer here.
