Instead, suppose that you assume the DGP (Y) to be normally distributed and, basedon a sample comprising persons 4, 8, 12, 16, and 20, produce an estimate of the pmf of Y. Basedon this estimated pmf/pdf, what is P({350

To solve this problem, we need to estimate the parameters of the normal distribution based on the…
