Exercise

Finding the slope of a linear regression

The US_fit object you created in the previous exercise is available in your workspace. Calling summary() on this gives you lots of useful information about the linear model.

What is the estimated slope of this relationship? Said differently, what's the estimated change each year of the probability of the US voting "yes"?
