Question 1184696: Let Y1, Y2, Y3, and Y4 be independent, identically distributed variables from a population with mean μ and variance σ(squared). let ȳ = 1/4(y1,y2,y3,y4) denote the average of these random variables. What are the expected value and variance in terms of μ and σ(squared)? Answer by robertb(5830) (Show Source):
