Directions

For you Lesson 6 Practice Hands-On, you will be calculating the answer to several questions. This Hands-On will not be graded, but you are encouraged to complete it. The best way to become a great Data Scientist is to practice! Please attach both your presentation and your R script in the below area.

Requirements

From the mtcars data frame, create a box plot of miles per gallon (the mpg variable) grouped by the number of cylinders in the engine (the cyl variable). Do these box plots make sense? Also, use the summarize() and group_by() functions to compute how many cars have four cylinders, how many have six, and how many have eight.

Prepare a report (using MS Power Point or similar) with all of these elements and any code used to arrive at the results.
