Problem 4 [5 points - Optional Question. Feel free to skip it.]. As you have seen in Problem 2B, we use a Chi-square test to fit Poisson Distribution. In general, the K-S test can be used to fit all different types of distributions, while the Chi-square test is only used to fit discrete distributions such as Poisson, Geometric, Hyper-geometric, and so on. Why do you think a Chi-square test only works for fitting discrete distributions? Explain
