Homework Statement
[itex] X_{1} , ..., X_{5} \textit{ iid } N( \mu , 1) \textit{ and } \hat{\mu} = \bar{X} [/itex]
where
[itex] L( \mu , \hat{\mu} ) = | \mu - \hat{\mu} | [/itex]
The Attempt at a Solution
[itex] E[ | \mu - \hat{\mu} | ] = 0 [/itex]
since
[itex] E(\hat{\mu}) = \mu [/itex]
Am I missing something? Seems too easy.
Should I be using Indicator functions to handle the absolute values?
Thanks for the help!
