Describe the general process for computing maximum likelihood estimates. Are there ever cases where there is ambiguity regarding the correct MLE?

Q:

=C (2 points) Let X1, ..., Xn be iid normal RVs with distribution N(u,02). What is the distribution of S =c+1=1 Xn, where c is a constant? If the X are not normal but are independent with means u and variance o>, what can be said about the distribution of S? =C (2 points) Let X1, ..., Xn be iid normal RVs with distribution N(u,02).
