If x 1 , x 2 , ……, x n are n values of a variable X and y 1 , y 2 , ……., y n are n values of variable Y such that y i = ax i + b, i = 1,2, ……, n, then write Var(Y) in terms of Var(X).

Question

Philoid · Accepted Answer

And, y_i=ax₁+b

Hence, proved

If x1, x2, ……, xn are n values of a variable X and y1, y2, ……., yn are n values of variable Y such that yi = axi + b, i = 1,2, ……, n, then write Var(Y) in terms of Var(X).

If x₁, x₂, ……, x_n are n values of a variable X and y₁, y₂, ……., y_n are n values of variable Y such that y_i = ax_i + b, i = 1,2, ……, n, then write Var(Y) in terms of Var(X).
