Getting to Work With Confidence: Visualize the Data

Donny doesn't like to wake up early, so he often arrives late to work. Donny blames his lateness on traffic. While Donny usually leaves home 10 minutes before work, and his commute takes 10 minutes on average, his commute often takes longer than 10 minutes. For a year, Donny, measures exactly how many minutes his morning commute takes, and records it in the vector Commute. Let's use this information to help Donny figure out when he should leave for work if he wants to arrive to work on time.

Instructions

100 XP
  • 1) Summarize the data in table form to see what information we have about Donny's commute.
  • 2) Visualize the data with a density plot to get a better sense for the distribution of his commute times.
