Question

You run a regression analysis on a bivariate set of data ( n = 89 ). With x ¯ = 48.6 and y ¯ = 76.3 , you obtain the regression equation y = - 3.417 x + 242.366 with a correlation coefficient of r = - 0.158 . You want to predict what value (on average) for the response variable will be obtained from a value of x = 80 as the explanatory variable. What is the predicted response value?

          You run a regression analysis on a bivariate set of data (
n
=
89
). With 
 
x
¯
=
48.6
 and 
 
y
¯
=
76.3
, you obtain the regression equation
y
=
-
3.417
x
+
242.366
with a correlation coefficient of 
r
=
-
0.158
. You want to predict what value (on average) for the response variable will be obtained from a value of 
x
=
80
 as the explanatory variable.

What is the predicted response value?
