Using a regression equation

Statistics
Tutor: None Selected Time limit: 1 Day

Exam score in Psy 1110 is used to predict nurses' salaries, and the regression equation turns out to be

ลท = 6(X) + 323

If a nurse earns a score of 80 on the exam, his/her predicted salary would be $____00.00? (Fill in the blank with the numbers only from solving the regression equation. Do NOT add additional zeros or decimal points.)

(Hint:  DO NOT convert 80 to a decimal for this problem!  Use the value of 80 (NOT .80) during your calculations.)

y=6x+323

the dependent variable is salary and independent variable is the test score, 

y=6(80)+323

y=480+323

y= $ 803
