# We want to calculate the statistical power to compare the distance between mutations on a DNA
# strand in two groups of people. Each group (X and Y) has 10 individuals. We assume that the
# distance between mutations in the first group is exponentially distributed with rate 3. We assume
# that the probability that the distance in the first group is less than the distance in the second
# group (i.e., P(X<Y)) is 0.8. The desired type I error is 0.05.
