X values 59, 65, 73, 80, 89

Y values 97, 102, 110, 117, 125

A) Accept p=0 because 60.81<3.18

B) Reject p=0 because 61.13>3.18

C) Accept p=0 because 61.13<2.78

Using 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.
