1. 5 pts. Try remaking the distributions from class, but with a lognormal function (use rgamma). In particular, have a look at the scale parameter and the rate parameter. What do these two parameters do? What does a high scale but low rate imply? A low scale bu high rate? Include your code below so I can reproduce the figures.
