No Belt 29                   20              49

Total       91                    52              143

Relative Frequency Table

            Watch                   No Watch            Total

Belt      62/94 = 0.66      32/94 = 0.34             94

No Belt 29/49 = 0.60      20/49 = 0.40            49

Total       91/143 = 0.63      52/143 = 0.36          143
