# Outliers

Suppose you have two observations, $y_1 =70$ and $y_2 = 100$, where $y_i = \mu + \epsilon$ with which to estimate the value of $\mu$, with $\epsilon_1 \tilde N(0,10)$ and $\epsilon_2\tilde \{(.5, -40), (.5, +40)\}$. What should our estimate $\hat{\mu}$ be?
I need to get the Math extension to work in Mediawiki. I have it in localsettings, so i just need it to update.
