You run a regression analysis on a bivariate set of data (n=101n=101). With ¯x=65.2x¯=65.2 and ¯y=42.7y¯=42.7, you obtain the regression equation y=−1.151x−20.497y=-1.151x-20.497 with a correlation coefficient of r=−0.017r=-0.017. You want to predict what value (on average) for the response variable will be obtained from a value of 190 as the explanatory variable. What is the predicted response value? y =
