Grade (in terms of the percentage of correct responses) in Psy 1110 is used to predict nurses' salaries and the regression equation turns out to be y = 7(X) + 393
If a nurse's predicted salary is eighty-nine thousand (for puposes of this problem, we're going to get rid of the extra 0's and represent the salary numerically as 890), what would be his or her grade in Psy 1110.
