You run a regression analysis on a bivariate (two-variable) set of data. You obtain the regression equation y = − 3.334 x + − 44.677 with a correlation coefficient of r = − 0.539 . You want to predict what value (on average) for the explanatory variable will give you a value of 160 on the response variable. What is the predicted explanatory value? x = (Report answer accurate to one decimal place.)

You run a regression analysis on a bivariate set of data ( n = 116 ). With ¯ x = 40.3 and ¯ y = 32.1 , you obtain the regression equation y = − 2.624 x − 19.502 with a correlation coefficient of r = − 0.522 . You want to predict what value (on average) for the response variable will be obtained from a value of 100 as the explanatory variable. What is the predicted response value? y = (Report answer accurate to one decimal place.)
