For example, red-haired people lost 50% of their losses on blackjack, 25% on craps, and 25% on poker. Brown-haired people lost 60% of their total losses on blackjack, 20% on craps and 20% on poker. Again, the underlying losses are different for each group and there are different numbers of people in each group. I also calculated the % of losses for ALL people collectively on each of the games. How would I determine if each group's losses are statistically different from all people collectively on each of these games?
