Question: During recent seasons, Major League Baseball has been criticized for the length of the

games. A report indicated that the average game lasts 3 hours and 30 minutes. A sample

of 17 games revealed the following times to completion. (Note that the minutes have

been changed to fractions of hours, so that a game that lasted 2 hours and 24 minutes

is reported at 2.40 hours.)

2.98 2.40 2.70 2.25 3.23 3.17 2.93 3.18 2.80

2.38 3.75 3.20 3.27 2.52 2.58 4.45 2.45

Can we conclude that the mean time for a game is less than 3.50 hours? Use the .05 significance level.
