### 10.1. Developing The Multiple Regression Model

In Chapter 9, when analyzing the moving company data, you used the cubic footage to be moved to predict the labor hours (CTQ). In addition to cubic footage (X1),

now you are also going to consider the number of pieces of large furniture (such as beds, couches, china closets, and dressers) that need to be moved (X2 = LARGE = number of pieces of large furniture to be moved). Table 10.1 presents the results.
