Question:

Consider the following observed values of (x_i, y_i): (1, 3), (3, 7).

a. Find the estimated regression line = Bo + Bx 61x

based on the observed data.

b. For each x_i, compute the fitted value of y_i using = Bo + Bixi. Yi

c. Compute the residuals, e_i = y_i − ^y_i.

d. Calculate R-squared.

e. Explain the above results. In particular, can you conclude that the obtained regression line is a good model here?
