Group Title
For a sample of eight bears, researchers measured the distances around the bear’s chests and weighed the bears. Minitab was used to find that the value of the linear correlation coefficient is r = 0.894. 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 explained by the linear relationship between weight and chest size?
Critical Values for the Correlation Coefficient
n alpha = .05 alpha = .01
4 0.95 0.99
5 0.878 0.959
6 0.811 0.917
7 0.754 0.875

100 0.196 0.256
Note: To test H subscript 0: rho equals 0 against H subscript 1: rho not equal to 0, reject H subscript 0 if the absolute value of r is greater than the critical value in the table.
