Discussion Questions For questions 1 and 2, think about the shapes of the two graphs, the probabilities, the relative frequencies, the means, and the standard deviations. 2. Describe the three most significant differences between the graphs or distributions of the theoretical, empirical, and simulation distributions. 3. Using your answers from questions 1 and 2, does it appear that the two sets of data fit the theoretical distribution? In complete sentences, explain why or why not. 4. Suppose that the experiment had been repeated 500 times. Would you expect Table 4.16 or Figure 4.6 to change, and how would it change? Why? Why wouldn’t the other table(s) change?
