I am looking through notes for confidence interval for the exponential

I have been given that:

f(y_i|t) = t^(-1) exp(-y_i/t).
We are then finding the maximum likelihood estimator ^t^, and with

Thank you all very much for your sensible replys. I was hoping to get
my marking done over the weekend, but I'm going to see the Course
Leader tomorrow and put my case to him and perhaps get a marking scheme
more suitable.
These are only first year assignments that don't count for much, but

and ported to Windows. They have a demo program available
for downloading too.

Neeraj,
It is easy to verify that if Y is exponential with mean t then Y/t is is
exponential with mean 1.
Also, the sum of n exponentials with parameter 1 has the distribution
Gamma(n,1). Most texts on probability and statistics (Feller Vol II, Mood
and Graybill) are references. It is a
