Program in R:
Generate 1000 exponential random deviates with the mean equal to ½. Be careful! The exponential is sometimes parameterized directly with the mean, B, using 1/B*exp(-x/B) and sometimes it is parameterized with the rate lambda = 1/B. Know what your software is doing. After generating the data, compute the mean and variance of the data. The mean and variance is all I need to see.
