The independent (predictor) variable is the bill amount and the type of bill which are represented by X in Figure. In analyzing all the data I was able to conclude that we did not need the type in the regression analysis, so based on that conclusion the following analysis are what I based my report on:
A) 1st Analysis – Overdue Bills Commercial
a. Scatter Plot Shows: Figure A
i. The higher the bill the less overdue it is, and the lower the bill the more overdue it is

i. Days = 101.7582 – 0.1910 * Bill ii. 95.7% of the data can be explained by using the commercial data with the independent variable of Bill. iii. The slope of -0.191 for each increase of one unit in x, the Y is estimated to increase
