Step 1
First, we need to find the slope (b1) of the estimated regression equation. To do this, we can use the formula: b1 = Σ[(xi - x̄)(yi - ȳ)] / Σ(xi - x̄)^2 where xi and yi are the individual data points, and x̄ and ȳ are the means of x and y, respectively. Show more…

1. In a simple linear regression model the data is given as X: 1, 2, 3, 4; Y: 7, 10, 9, 12. The estimated intercept is 6. The estimated slope is 1.4. The sum of residuals is: A. 38 B 5 C 0 D 3.2 2. In a simple linear regression model the data is given as X: 2, 6, 11, 13, 20; Y: 7, 18, 9, 26, 25. The estimated intercept is: A. 7.38 B 1.81 C 0.92 D 6.17
