562/2=281
You are playing a paired dice game with your brother, and he has placed all his bets
on the extreme number (2s, 3s, 11s, and 12s) whereas you placed your bets on the
middle numbers (5s, 6s, 7s, and 8s). However, as the game goes on, you think that
the dice are landing on the extreme numbers more often than should be allowed
strictly by chance. In fact, he's winning! You accuse him of using a loaded dice, and
in order to test it, you keep track of all the dice rolls for 100 rolls and run a Chi-
Square analysis. The p-value you get back is 0.47. Which of the following
conclusions should you draw?
A. Your brother is definitely cheating.
B. Your brother is most likely cheating.
C. Your brother is probably not cheating.
D. Your brother is definitely not cheating.✔✔C. Your brother is probably not
cheating.
