**MathGuru**, Tuesday, May 8, 2012 at 4:41pmUsing an online calculator with the following pairs:

5 data pairs (x,y):

( 59.0 , 97.0 ); ( 65.0 , 102. ); ( 73.0 , 110. ); ( 80.0 , 117. ); ( 89.0 , 125. );

Degrees of freedom = N (number of pairs) - 2 = 3

Correlation coefficient r = 1.00

Check the appropriate table for degrees of freedom and the level of significance to determine whether or not to reject the null.
