Suppose you’re playing a dice game in which two 6-sided dice are thrown, and players win when the sum of the values appearing on the dice is at least 7. In the last 100 games, you’ve noticed that players have won 95 times. Do you have any reason to believe that the dice are unfairly weighted using the central limit theorem? I have understood up to getting z=7.434. But how do you know to find P(z>7.434) and not use P(x<7.434)....
