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 116 pounds? Use a significance level of 0.05. Chest size (inches) 44 41 41 55 51 42 D Weight (pounds) 213 206 176 309 300 178 Click the icon to view the critical values of the Pearson correlation coefficient r. - What is the regression equation? ĝ=+ Nx (Round to one decimal place as needed.)
