For a sample of eight​ bears, researchers measured the distancesaround the​ bears' chests and weighed the bears. Minitab was usedto find that the value of the linear correlation coefficient isr=0.931 Using alphaα=​0.05, determine if there is a linearcorrelation between chest size and weight. What proportion of thevariation in weight can be explained by the linear relationshipbetween weight and chest​ size?
a. Is there a linear correlation between chest size and​weight?
A.​Yes, because the absolute value of r exceeds the criticalvalue of 0.707
B.​No, because the absolute value of r exceeds the criticalvalue of 0.707.
C.​Yes, because r falls between the critical values of −0.707and 0.707.
D. The answer cannot be determined from the giveninformation.
b. What proportion of the variation in weight can be explainedby the linear relationship between weight and chest​ size?
