For a sample of eightbears, researchers measured the distances around thebears' chests and weighed the bears. Minitab was used to find that the value of the linear correlation coefficient is r=0.815. Using =0.05, determine if there is a linear correlation between chest size and weight. What proportion of the variation in weight can be explained by the linear relationship between weight and chestsize?

For a sample of eight bears, researchers measured the distances around the bears' chests and weighed the bears. Minitab was used to nd that the value of the linear correlation coefcient is r= 0.815. Using 0: = 0.05, determine if there is a linear correlation between chest size and weight. What proportion of the variation in weight can be explained by the linear relationship between weight and chest size? Click here to view a table of critical values for the correlation coefcient. a. Is there a linear correlation between chest size and weight'.7 O A. Yes, because the absolute value of the test statistic exceeds the critical value of 0.707. O B. No, because the absolute value of the test statistic exceeds the critical value of 0.707. O c. Yes, because the test statistic falls between the critical values of - 0.707 and 0.707. O D. The answer cannot be determined from the given information
