Question

Using the regression equation below, predict a person's Y score using x = 15. Y = .25x - 7

Answer 1

Using the regression equation Y = .25x - 7 and substituting x with 15, the predicted Y score would be -3.25.

Step-by-step explanation:

To predict a person's Y score using x = 15 and the regression equation Y = .25x - 7, we plug the value of x into the equation:

Y = 0.25(15) - 7

Y = 3.75 - 7

Y = -3.25

So, using the regression equation, a person with an x value of 15 would have a predicted Y score of -3.25.
