## Statistics

To test whether the mean length is significantly less than a given value.

Throughout 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 2.4 2.7 2.25 3.23 3.17 2.93 3.18 2.8 2.38 3.75 3.2 3.27 2.52 2.58 4.45 2.45

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