Identify a numeric IV that you think could explain our DV, favorability toward big business. Compute the linear model. Interpret the results, as appropriate. We'll see which group has the best fitting model (explains the most variation in our DV). Paste your R code below your interpretation.

- For every 10 degree change in favorability toward poor people, you can expect a 3.7 degree change in favorability toward big business. We can explain 7% of explained variation for big business.

There is a significant difference, we reject the null hypothesis, for a ten degree change in favorability toward police there would be a 2.4 degree change in favorability toward big business.
we can only explain 3 percent
we can only explain 3 percent of variation in this model.
