1. 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 equals=0.868 Using Alpha equals=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? What proportion of the variation in weight can be explained by the linear relationship between weight and chest size?

Solution

a. A

b. .976^2= .95276 or .953 to 3 decimal places.
