Explanation Given: Suppose that distributions X and Y have means x ¯ and y ¯ respectively. Calculation: It is given that distributions X and Y have means x ¯ and y ¯ respectively. By definition, x ¯ = ∑ x n 1 and y ¯ = ∑ y n 2 By definition the mean of the distributions X + Y is given by, X + Y ¯ = ∑ x + ∑ y n 1 + n 2 From x ¯ =
