What does the textbook say about your ability to use regression analysis in your management capacity after you've studied chapter $3?$

$"$If you study this material carefully and practice it in your economics course, you will have the ability to perform virtually any kind of statistical regression analysis your company will need. With these tools, your company can...avoid the unnecessary cost of hiring so$-$called 'experts' and econometric specialists."
