QUESTION 1 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.) Quit Smoking Yes No Treatment Group Reward 156 758 Deposit 78 68 Use this table to answer Problems 1-4. 1) How many people in the study had quit smoking after six months? Calculate the difference in proportion who quit smoking, , between those in the Deposit program and those…
Suppose a company charges a premium of $150 per year for an insurance policy for storm damage to roofs. Actuarial studies show that in case of a storm, the insurance company will pay out an average of $8000 for damage to a composition shingle roof and an average of $12,000 for damage to a shake roof. They also determine that out of every 10,000 policies, there are 7 claims per year made on composition shingle roofs and 11 claims per year made on shake roofs. What is the company’s expected value (i.e., expected profit) per year of a storm insurance policy? What annual profit can the company expect if it issues 1000 such policies? Determine the probability of a composition shingle roof claim out of 10,000 = ______ Determine the probability of a shake roof claim out of 10,000 = ______ How many claims are made out of 10,000? = _______ What is the probability of no claims out of 10,000? = _______ How much does each shingle roof claim cost the company, don’t forget each person pays $150…
