If a constant c is added to each ï¿ in a sample, yielding yį = x;+c, how do the sample mean and median of the y; s relate to the mean and median of the x₂ s? Verify your conjectures. If each ï¿ is multiplied by a constant c, yielding Yi : question of part (a). Again, verify your conjectures. = CXi, answer the
