Question

10. For the following experiment, indicate whether it was single-blind, double-blind, or not blinded at all. Explain your reasoning. Does a stop smoking program work better if it costs more? Smokers responding to an advertisement offering to help them stop smoking were randomly offered a program

costing $100 or the same program costing $250. The offer idually to each client by resenting a Seale envelope so the clerk providing the offer did not know the de- tails of the offer. At the end of the program (a course and films along with diet and smoking cessation aids), clients were fol- lowed for six months to see if they had indeed quit smoking.
