Financial Incentives to Quit Smoking This exercise deals with an experiment to study the effects of financial incentives to quit smoking1. Smokers at a company were invited to participate in a smoking cessation program and randomly assigned to one of two groups. Those in the Reward group would get a cash award if they stopped smoking for six 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. Agreeing to Participate The random assignment at the start of the experiment put 1017 smokers in the Reward group and 914 of them agreed to participate. However only 146 of the 1053 smokers assigned to the Deposit group agreed to participate (since they had to risk some of their own money). Fill in the following two-way table and compare the participation rates between subjects assigned to the two treatment groups. Round your answers for the participation rates to three decimal places.
