Again, apologies for non LaTex, im trying to learn i promise!
Pretty much no idea where to start with this one....
In an experiment we take 26 observations Xi from a normal distribution with unknown mean "mu" and variance 15
From this sample we find that
26
Sum of = 360
i=1
Using this data, what is the MLE of "mu"?
Using the invariance property of MLE, what is the MLE of Z = 2/(mu+6)
