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 = 0.921. using α = 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?
a) is there a linear correlation between chest size andweight? b) what proportion of the variation in weight can be explainedby the linear relationship between weight and chest size?
