You run a regression analysis on a bivariate set of data ($n = 20$). With $\bar{x} = 77.2$ and $\bar{y} = 63.9$, you obtain the regression equation \begin{equation*} y = -0.486x + 101.419 \end{equation*} with a correlation coefficient of $r = -0.271$. You want to predict what value (on average) for the response variable will be obtained from a value of $x = 80$ as the explanatory variable. What is the predicted response value? $y = $

You run a regression analysis on a bivariate set of data (n = 91) with x̄ = 66.8 and ȳ = 40.1. You obtain the regression equation y = 4.034x - 28.828 with a correlation coefficient of r = 0.046. You want to predict what value (on average) for the response variable will be obtained from a value of 140 as the explanatory variable. What is the predicted response value? (Report answer accurate to one decimal place.)
