Question: Sports and Leisure. The mean duration of a Major League baseball game from the first pitch to the last out over the first eight weeks of the 2013 season was 2 hours and 58 minutes.

A random sample of second-half games will be selected, and the resulting game durations will be used to determine whether games take less time to complete.
