Consider a sample ₁, 2,...,n and suppose that the values of and s² have been calculated.Let y₁ = axi + b for i=1,2,. n. How do the sample mean and the sample variance of theyi's relate to and s² respectively? Verify your conjectures.

ANSWER:- The sample mean y is (1/n) * Σy_i = (1/n) * Σ (ax_i + b) = (a / n) * Σx_i + (b / n) * n = a…
