Smokers at a company were invited to participate in a smoking cessation program, and were randomly assigned to one of two groups. Those in the Reward group would get a cash award if they stopped smoking for 6 months. Those in the Deposit group were asked to deposit some money which they would get back along with a substantial bonus if they stopped smoking for 6 months. After six months, 156 of the 914 smokers who accepted the invitation to be in the reward-only program stopped smoking, while 78 of the 146 smokers who paid a deposit quit. A two-way table for this data is given below. (Be careful: "Total" rows/columns are not included.)
