The random variable X is uniformly distributed in the interval [0, α] for some α > 0. Parameter α is fixed but unknown. In order to estimate α, a random sample X1, X2, . . . , Xn of independent and identically distributed random variables with the same distribution as X is collected, and the maximum value Y = max{X1, X2, ..., Xn} is considered as an estimator of α.

(a) Derive the cumulative distribution function of Y .



(b) Find the mean and variance of Y , and explain why Y is a good estimator for α when sample size n is large.
