Marginal and conditional histograms

Now, turn your attention to a new variable: horsepwr. The goal is to get a sense of the marginal distribution of this variable and then compare it to the distribution of horsepower conditional on the price of the car being less than $25,000.

You'll be making two plots using the "data pipeline" paradigm, where you start with the raw data and end with the plot.

Instructions

100 XP
  • Create a histogram of the distribution of horsepwr across all cars and add an appropriate title. Start by piping in the raw dataset.
  • Create a second histogram of the distribution of horsepower, but only for those cars that have an msrp less than $25,000. Keep the limits of the x-axis so that they're similar to that of the first plot, and add a descriptive title.
