Problem 3 Recall that X ~ Exp(A) if the probability density function of X is fX(x)-Ae-λ r for z 2 0, Let Xi, , Xn ~ Exp(A), where λ is an unknown parameter. Exponential random variables are often used to model the time between rare events, in which case λ is interpreted as the average number of events occurring per unit of time a) Let zı, . . . , en be n observations of an...
