You run a regression analysis on a bivariate set of data (n=80). With x¯=78.4 and ¯y=56.8, you obtain the regression equation y = 3.267x−199.333 Nwith a correlation coefficient of r=0.121.  You want to predict what value (on average) for the response variable will be obtained from a value of x=50 as the explanatory variable. What is the predicted response value? y =  (Report answer accurate to one decimal place.)
