Compute the linear regression equation for predicting Y from X for each of the data sets in Exercise 3 in Chapter 9. What proportion of the variance in Y is accounted for by X in each data set? For each data set, use the appropriate formula to calculate the unbiased standard error of the estimate (s_est).
