2. Find probability that fewer 0.19 of the sample smokes: a) Using the 68-95-99.7 Rule. Make sure to sketch the density curve and shade the area of interest. (2 pts) b) Using the results of the simulation. (1 pt) 3. Find probability that between 0.18 and 0.22 of the sample smokes: a) Using the 68-95-99.7 Rule. Make sure to sketch the density curve and shade the area of interest. (2 pts) b) Using the results of the simulation. (1 pt) 4. Are the results for parts a) and b) EXACTLY the same for questions #1, #2, #3 above? (1 pt) 5. Why is there a difference between the results for parts a) and b) for each question above? (1 pt) 6. What would happen to the results for parts a) and b) if we simulated 50000 samples of size n = 1600 from a
