This manual provides answers and solutions to some 475 questions

and problems in the fourth edition of Basic Econometrics. Most of the

answers and solutions are given in detail. In a few cases where detailed

answers were not necessary, I have provided some guidance.

Providing the solutions has been a tedious and time-consuming task.

I have made every effort to check the accuracy of the solutions but some

numerical errors and inaccuracies and misprints may have crept in. I would

appreciate it very much if the reader will bring them to my attention so that

I can correct them in the reprints of this manual.
