An investigator believes that students who rank high in certain kinds of motives will behave differently in gambling situations. To investigate this hypothesis, the investigator randomly samples 50 students high in affiliation motivation, 50 students high in achievement motivation, and 50 students high in power motivation. The students are asked to play the game of roulette, and a record is kept of the bets they make. The data are then grouped into the number of subjects with each kind of motivation who make bets involving low, medium, and high risk. Low risk means they make bets involving low odds (even money or less), medium risk involves bets of medium odds (from 2 to 1 to 5 to 1), and high risk involves playing long shots (from 17 to 1 to 35 to 1).

The following data are obtained:
