[16 pоints оn Grаdescоpe] Suppose thаt Y1,...,Yn{"version":"1.1","mаth":"Y1,...,Yn"} denote a random sample from an exponentially distributed population with mean θ{"version":"1.1","math":"θ"}. Find the MLE of the population variance θ2{"version":"1.1","math":"θ2"}. SHOW ALL YOUR WORK HINT: Remember that exponential distribution is f ( x ; θ ) = 1 θ e − x / θ , x > 0 , θ > 0
