Question 1064230
y hat=2.88 x1+1.86 x2-114; x1=female's height in inches (note editing, is this what you meant?) and x2= body fat in %
2.88(67)+1.86(28)-114=
192.96+52.08-114=245.04-114=131.04 pounds.
y hat is the predicted body weight as a function of two variables (height and body fat) minus a constant 114.

I think this is what you meant, and the answer would appear to make sense, but re-submit if this isn't what you wanted.
