  1. Using the same binwidth from #3, plot a histogram with lightseagreen lines and aquamarine3 shaded areas. Then overlay a density plot with a aquamarine4 line with width 2.

  1. What is the difference between a frequency polygon and a density plot?

  2. Make a density plot with bandwidth of 3 and separate line colors for different cylinder levels.

  1. Repeat #6 but also include separate colors for the shaded areas with a transparency of 0.5. Use viridis colors for both lines and shaded areas, and reverse the direction of the colors where 4 is yellow, 6 is greenish, and 8 is purplish.
