Determine the sum of squares of error (SSE) and the standard error of the estimate (se) for Problem 12.6. Determine how many of the residuals computed in Problem 12.14 are within one standard error of the estimate. If the error terms are normally distributed, approximately how many of these residuals should be within ± 1se?
