Question 2 In this problem we use inverse transform sampling to randomly sample from an exponential distri- bution. The inverse of a cumulative distribution function is sometimes called a \"quantile function.\" Given an input 3;, the quantile function for a distribution tells us the value of a random variable of that distribution such that the probability of the variable being less than or equal to that value equals 1:. (a) Derive the inverse of the exponential CDF 1 6)'1
