8:09 PM Mon Nov 7 '' 55% I . b) Using the results of the simulation. (HINT: Use the table you completed on page one!) 2. Find probability that fewer 0.19 of the sample smokes: a) Using the 6895997 Rule. Make sure to sketch the density curve and shade the area ofinterest. b) Using the results of the simulation. (HINT: Use the table you completed on page one!) 3. Find probability that between 0.18 and 0.22 of the sample smokes: a) Using the 6895997 Rule. Make sure to sketch the density curve and shade the area of interest. 8:09 PM Mon Nov 7 '1? 55% I . 0 0 O O (> 0 Using the 6895-997 Rule, what is the probability that at least 22% (0.22) of the sample smoked a cigarette in the past week? Using the results of the simulation, what is the probability that at least 22% (0.22) of the sample smoked a cigarette in the past week? Using the 6895-99] Rule, what is the probability that fewer than 19% (0.19) of the sample smoked a cigarette in the past week? Using the results of the simulation, what is the probability that fewer than 19% (0.19) of the sample smoked a cigarette in the past week? Using the 6895-99] Rule, what is the probability that 18% to 22% (between 0.18 and 0.22) of the sample smoked a cigarette in the past week? Using the results of the simulation, what is the probability that 18% to 22% (between 0.18 and 0.22) of the sample smoked a cigarette in the past week? Are the probabilities from the 68-95-99] Rule exactly the same as the probabilities from the results of the simulation for the three events described above? Answer yes or no. Explain your answer to the previous question. What would happen to the probabilities from the results of the simulation if we simulated 50000 samples of 1600 adults instead of 1000 samples of 1600 adults? What statistical principle explains the answers to the two previous questions? A. B. C. D. L-_-_Im.'"'!"" EUOTUOZEFZ yes no The Law of Lucky Results If we simulate 50000 samples of 1600 adults instead of 1000 samples of 1600 adults nothing would change since we are sampling 1600 adults in each case. 0.16 The Law of Large Numbers . 0.05 .176 0.028 The probabilities from the simulation are exactly the same as the probabilities from the 6895997 Rule. Since the events are the same, the probabilities will be the same no matter how we compute them. 0.32 0.025 .0943 . 0.68 . 68-95-997 Rule 0.997 . 0.95 The probabilities from the simulation are close to the probabilities from the 68-95-99] 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. 0.175 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 6895-99,?
