This case of study aims to strengthen the ability of the reader to systematically solve issues that involve
using econometric tools. We focus on the linear regression model. The problem is about the estimation of a
demand curve, which leads to hypothesis testing for a linear regression model. The discussion deals with a
problem that seems to be taken for granted, and it also mentions the importance of considering theoretical
implications when using one- and two-tailed tests.
