Exercise

Simulating multiplying a random variable

In this exercise you'll use simulation to confirm the rule you just learned about how multiplying a random variable by a constant effects its expected value.

Instructions

100 XP

Simulate 100,000 draws of X, a binomial random variable with size 20 and p = .1. Save this as X
Use this simulation to estimate the expected value of X.
Use this simulation to estimate the expected value of 5*X, as well.
