In a population of 10,000, there are 5000 nonsmokers, 2500 smokers of one pack or less per day, and 2500 smokers of more than one pack per day. During any month, there is a 5% probability that a nonsmoker will begin smoking a pack or less per day, and a 4% probability that a nonsmoker will begin smoking more than a pack per day. For smokers who smoke a pack or less per day, there is a 10% probability of quitting and a 10% probability of increasing to more than a pack per day. For smokers who smoke more than a pack per day, there is a 5% probability of quitting and a 10% probability of dropping to a pack or less per day. How many people will be in each group in 1 month, in 2 months, and in 1 year? (Round your answers to the nearest whole number.)

(a) in 1 month

nonsmokers   people
1 pack/day or less people
more than 1 pack/day     people


(b) in 2 months

nonsmokers people
1 pack/day or less people
more than 1 pack/day     people


(c) in 1 year

nonsmokers people
1 pack/day or less people
more than 1 pack/day     people

A medical researcher compares the pulse rates of smokers and nonsmokers. A sample of 71 smokers had a mean pulse rate of 81. A sample of 86 nonsmokers had a mean pulse rate of 77. Assume the standard deviation of the pulse rates is known to be 7 for smokers and 7 for non- smokers. Using these results, conduct a hypothesis test of the conjecture that the true mean pulse rate for smokers is different from the true mean pulse...

Chimnesia has two equally sized groups of people: smokers and nonsmokers. Both types of people have utility U =sqrt(C), where C is the amount of consumption that people have in any period. So long as they are healthy, individuals will consume their entire income of $16,000. If they need medical attention (and have no insurance), they will have to spend $12,000 to get healthy again, leaving them with only $4,000 to consume. Smokers have a 10% chance of requiring major...
