You run a regression analysis on a bivariate set of data (n=81n=81). With ¯x=33.6x¯=33.6 and ¯y=80.6y¯=80.6, you obtain the regression equation

y=−2.744x+43.641y=-2.744x+43.641

with a correlation coefficient of r=−0.045r=-0.045. You want to predict what value (on average) for the response variable will be obtained from a value of 130 as the explanatory variable.

What is the predicted response value?
