Step 1

Given: xi: 1, 2, 3, 4, 5 yi: 3, 8, 4, 12, 13 Mean of x (x̄) = (1 + 2 + 3 + 4 + 5) / 5 = 3 Mean of y (ȳ) = (3 + 8 + 4 + 12 + 13) / 5 = 8 Show more…

Develop the estimated regression equation by computing the values of b0 and b1 using b1 = ̃́(xi − x)(yi − y) / ̃́(xi − x)² and b0 = y − b1x. ŷ = (e) Use the estimated regression equation to predict the value of y when x = 4.
