Exam score (X) is used to predict nurses’ salaries (?), and the regression equation turns out to be:
? = 8(X) + 332
If a nurse’s predicted salary (?) is $890 per week (for purposes of this problem, represented numerically as 890), what would be his or her exam score (X)?
(Hint: Note that in this particular problem, you are solving for X . . . not for ?)
