PROJECT PART C: Regression and Correlation Analysis Math-533 Applied Managerial Statistics Prof. Jeffrey Frakes December 12‚ 2014 Jared D Stock 1. Generate a scatterplot for income ($1‚000) versus credit balance ($)‚ including the graph of the best fit line. Interpret. This scatter plot graph is a representation of combining income and credit balance. It shows the income increasing as the credit balance increases. As a result of this data it can be inferred that there is

Course Project Part Three Professor Douglas Nottingham March 27‚ 2014 1. Generate a scatterplot for CREDIT BALANCE vs. SIZE‚ including the graph of the "best fit" line. Interpret. The larger the size of the family the larger the credit balances is for the family. The larger families have the financial needs to have a larger credit balance. 2. Determine the equation of the "best fit" line‚ which describes the relationship between CREDIT BALANCE and SIZE. Credit Balance ($)
