1. Generate 20 observations from a standard normal distribution, and store them in the R variable ep. Repeat this, and store the values in x. Compute y=x+ep, and compute Kendall’s tau. Generally, what happens if two pairs of points are added at (2.1, −2.4)?

Does this have a large impact on tau? What would you expect to happen to the p-value when testing H0: τ = 0?
