Assignment 3
1. A sample of n independent observations, X1,X2,.,Xn, is taken from
a normally distributed population. To estimate the population mean
consider three estimators: G, H and M, such that
G = X1, H = (X1 + X2)/2, M = (X1,X2,.,Xn)/n,

may bet $1 on any number, and will win $32 plus the return of his bet if the
ball lands on the chosen number, otherwise he loses his bet. The wheel is spun
