Solution-
After running the regression analysis in the excel, we obtain the following regression output-
A. Slope = 1.90323
B. It means that when value of X increases by 1, then value of Y increases by 1.90323
C. Regression equation is-
Y = -1.419 + 1.90323 * X
D. Yes it would be appropriate when X=10 to be calculated using model.
When X = 10, then Y = -1.419 + 1.90323 * 10
= 17.6133
E. e1 = Actual value - predicted value
= -2 - ( -1.419 + 1.90323 * 1)
= -2.484

Data on the fuel consumption ?y of a car at various speeds ?x is given. Fuel consumption is measured in mpg, and speed is measured in miles per hour. Software tells us that the equation of the least‑squares regression line is ?̂ =55.3286−0.02286?y^=55.3286−0.02286x Using this equation, we can add the residuals to the original data.
