The following sample observations were randomly selected. (Round intermediate calculations and final answers to 2 decimal places.) x: 4 5 3 3 10 y: 4 6 5 3 7 A..The regression equation is ŷ =+xb.When x is 6 this gives ŷ = ? + ?x B. When x is 6 this gives ŷ = ?

Given data: n = 5 Σx = 25 Σy = 25 Σx^2 = 159 Σy^2 = 135 Σxy = 140 Calculate the slope (b1): b1 = (Σxy - (Σx * Σy) / n) / (Σx^2 - (Σx)^2 / n) b1 = (140 - (25 * 25) / 5) / (159 - (25)^2 / 5) b1 = (140 - 125) / (159 - 125) b1 = 15 / 34 ≈ 0.4412 Calculate the Show more…
