Referring to the earthquake data in Exercise 2.20,
(a) Obtain a five-number summary: minimum, Q₁, Q₂, Q₃, maximum.
(b) Construct a boxplot.

Data from in Exercise 2.20

In a recent year, 35 sites around the world experienced earthquakes of magnitude greater than 6.5.

Construct a histogram using equal-length intervals starting with (6.5, 6.8 ], where the right-hand endpoint is included but not the left-hand endpoint.
