Empirical Analysis in Finance / Econometrics

[Hint: In some exercises, you might need to use the NORM.DIST and/or NORM.INV functions in Excel. For example, let a random variable X follow a normal distribution with mean 10 and standard deviation 20. If you are asked to compute the probability that a data value drawn from that distribution is below 8, you enter NORM. DIST(8, 10,20,1) to obtain 46%. Or, if you want to find x such that 90% of the population have the data value below x, or Pr(X
