You run a regression analysis on a bivariate set of data (n=52 ). With ¯x=57.9 and ¯y=77.2 , you obtain the regression equation y=−1.976x+17.271 with a correlation coefficient of r=−0.232. You want to predict what value (on average) for the response variable will be obtained from a value of 150 as the explanatory variable.
