A Question Help O The data show the chest size and weight of several bears. Find the regression equation, letting chest size be the independent (x) variable. Then find the best predicted weight of a bear with a chest size of 39 inches. Is the result close to the actual weight of 126 pounds? Use a significance level of 0.05.

Question 4 > You run a regression analysis on a bivariate set of data (n = 11). You obtain the regression equation y = 3.4118 + - 32.224 with a correlation coefficient of r = 0.947 (which is significant at a = 0.01). You want to predict what value (on average) for the explanatory variable will give you a value of 70 on the response variable. What is the predicted explanatory value?
