The Roller Coaster Database maintains a website (www.rcdb.com) with data on roller coasters around the world. Some of the data recorded include whether the coaster is made of wood or steel, and the maximum speed achieved by the coaster in miles per hour. The box plots display the distributions of speed by type of coaster for 145 coasters in the United States as downloaded from the site in November 2003.


Which type of roller coaster has a higher percentage of coasters that go faster than 50 mph?



Wooden



Steel



There are an equal proportion of both types of roller coasters reaching this speed.



This is impossible to determine from the box plots.
