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 requals
=0.773
0.773. 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 chestsize?

a. Is there a linear correlation between chest size andweight?
A.
No, because the absolute value of the test statistic exceeds the critical value of 0.707
of0.707.
B.
Yes, because the test statistic falls between the critical values of negative 0.707
0.707 and 0.707.
C.
Yes, because the absolute value of the test statistic exceeds the critical value of 0.707
of0.707.
D.
The answer cannot be determined from the given information.
