Suppose that X1,...,Xn are normal with mean #1; 1/1,...,Y.n are normal with mean #2; and W1,...,Wn are normal with mean #1 + #2. Assuming that all 371 random variables are independent with a common variance, nd the maximum likelihood estimation of m and #2- 5. Let X1,...,Xn be a sample from the distribution whose density function is e_('\"_9) I>9 m 0 otherwise Determine the maximum likelihood estimator of 6
