A machine releases a candy-bar with unknown probability q at a press of a button (each press is independent on others). Clearly, the number of attempts required to receive one bar is distributed according to Geo(q). Your sweet-tooth instructor wants n candy bars, which would take him an overall of Sn := X1 + X2 + . . . + Xn attempts. Here X1, . . . , Xn ∼ Geo(q) are independent. A) Find the moment estimator of q...
