Expected value

[Jonny]

Hi! I do not understand how the expected value of E(µ) is equal to my. I understand almost all steps, but not the last one. Can someone explain how ((1/n) sum(µ)) can be µ

Since \(\displaystyle \mu\) is a constant we have:

\(\displaystyle \sum_{i=1}^n\mu \ \ \to \ \ \mu + \mu +\mu... = n * \mu \)
