Question 753261
Grade (in terms of percentage of correct responses) in PSY 1110 is used to predict nurses'salaries and the regression equation turns out to be 
y=7(X)+385
Note: X is the percentage ; Y is salary
-----------------------------------------
If a nurse's predicted salary is eighty-nine thousand ( for purposes of this problem, represented numerically as 890) What would be his or her grade in PSY 110.
-------------
Solve: 890 = 7x + 385
7x = 505
x = 72.14 (her grade)
