Given are five observations for two variables, x and y. xi 3 12 6 20 14 yi 55 40 55 10 15 Develop the estimated regression equation by computing the values of b0 and b1 using b1 = Σ(xi - x)(yi - y) / Σ(xi - x)^2 and b0 = y - b1x. ŷ = (e) Use the estimated regression equation to predict the value of y when x = 10.

Step 1
The mean of x (x̄) = (3 + 12 + 6 + 20 + 14) / 5 = 11 The mean of y (ȳ) = (55 + 40 + 55 + 10 + 15) / 5 = 35 Show more…

In a regression analysis involving 30 observations, the following estimated regression equation was obtained. $$\hat{y}=17.6+3.8 x_{1}-2.3 x_{2}+7.6 x_{3}+2.7 x_{4}$$ a. Interpret $b_{1}, b_{2}, b_{3},$ and $b_{4}$ in this estimated regression equation. b. Predict $y$ when $x_{1}=10, x_{2}=5, x_{3}=1,$ and $x_{4}=2 .$
