Question

Bigelow Roofing is developing a model to help its estimators bid on new roofing jobs. Below is output from a regression analysis attempting to link the dependent variable y (labor cost) to independent variables x1 (area of the roof), x2 (pitch of the roof), and x3 (number of special areas such as porches, skylights, etc.) using a sample of seven recent jobs. Partial results from the analysis are shown below. Compute the value of the adjusted r 2 and explain what it represents.
