Answers may be used once, more than once or not at all. A Using the 68-95-99] Rule, what is the probability that A. yes 7 v at least 22% (0.22) of the sample smoked a cigarette B in the past week? ' no , C Using the results of the simulation, what is the C- The Law Of Lucky RESUltS probability that at least 22% (022) Of the sample D. If we simulate 50000 samples of 1600 adults instead of smoked a cigarette m the past week? 1000 samples of 1600 adults nothing would change since , C Using the 68-95-99] Rule, what is the probability that . . fewer than 19% (0.19) of the sample smoked a we are sampling 1600 adults In each case. cigarette in the past week? E- 0-15 _ c Using the results of the simulation, what is the F. The Law of Large Numbers probability that fewerthan 19% (0.19) of the sample G 0 05 smoked a cigarette in the past week? ' ' , c Using the 63-95-99,? Rule, what is the probability that H' '76 18% to 22% (between 0.18 and 0.22) of the sample I. 0.028 smoked a Cigarette m the past week? _ J. The probabilities from the simulation are exactly the 7 C Usrng the results 00f the S'TUlatlon' what '3 the same as the probabilities from the 68-95-997 Rule. Since probability that 18 /D to 22 A) (between 018 and 022) the events are the same the robabilities will be the of the sample smoked a cigarette in the past week? ' p , 3 Are the probabilities from the 68-95-99] Rule exactly same no matter how we compute them. the same as the probabilities from the results of the K. 0.32 simulation for the three events described above? L 0 025 Answer yes or no. ' ' , 3 Explain your answer to the previous question. M' 0943 N. 0.68 _ C What would happen to the probabilities from the results of the simulation if we simulated 50000 0' 68'95'99'7 Rule samples of 1600 adults instead of 1000 samples of P. 0.997 1600 adults? Q. 0.95 ' C What statistical principle explains the answers to the R The probabilities from the simulation are close to the two previous questions? probabilities from the 689599] Rule but they are not exactly the same because sample proportions vary slightly from sample to sample and although we have 1000 samples, which is a large number, the results will not be exactly the same. 5. 0.175 T. If we simulate 50000 samples of 1600 adults instead of 1000 samples of 1600 adults the probabilities from the simulation would be closer to the probabilities from the 689599] Rule.
