Out of 40 bad male golfers, 20 say dry and 20 said fine. Out of 10 good female golfers, 1 say dry and 9 say fine. Out of 90 bad female golfers, 39 say dry and 51 say fine. Fill in the following cross-tabulation table. Construct a separate cross-tabulation row % table. Which group, male or female show the highest % saying the grass is too dry?
