In a popular British television program the final round requires each of two contestants to choose “split” or “steal.” If both choose “split”, they share the jackpot equally. If both choose “steal”, they both win nothing. If one chooses “split” and the other chooses “steal”, the person “stealing” wins the entire jackpot. The following table lists the choices of several programs based on age. Is there a significant statistical difference between the two groups?
Split Steal
Under 40 187 195
Over 40 116 76
somebody please help! I have no idea which hypothesis test to use?
