In this analysis I will be working with the 'mtcars.csv' data file and will be performing two multiple regressions, both will have an interaction term and one will also have a qualitative term. I will also create several plots from the data garnered from the regressions, fitted values against residuals, Q-Q norm plot, and using our models to make predictions. This data file contains a set of variables that are considered to influence the fuel economy of a vehicle. Information collected from this research could be used by car producers/designers to determine which variable has the most effect on a vehicle's fuel efficiency
