For a sample of eight bears, researchers measured the distances around the bears' chests and weighed the bears. Minitab was used to find that the value of the linear correlation coefficient is r= 0.833. Using a = 0.05, determine if there is a linear correlation between chest size and weight. What proportion of the variation in weight can be explaine by the linear relationship between weight and chest size? Click here to view a table of critical values for the correlation coefficient. a. Is there a linear correlation between chest size and weight? O A. Yes, because the absolute value of r exceeds the critical value of 0.707. O B. No, because the absolute value of r exceeds the critical value of 0.707. O C. Yes, because r falls between the critical values of - 0.707 and 0.707. O D. The answer cannot be determined from the given information. 6. What proportion of the variation in weight can be explained by the linear relationship between weight and chest size?
