Researchers recorded data on the amount of sleep reported each night during a week by a random sample of 20 high school students. Here are parallel boxplots comparing the distribution of time slept on all 7 nights of the study:

Use the graph to help answer the following questions.

a. Which distributions have a clear left-skewed shape?

b. Which outlier stands out the most, and why?

c. How does the typical amount of sleep that the students got compare on these seven nights?
