A team manager has to select a runner for the 100m sprint. He has two athletes in mind.
Here are the race times this season:

Athlete A - 14.2 14.8 13.8 15.1 14.1

Athlete B - 14.4 14.3 14.6 14.2 14.5

Using an appropriate average, determine which athlete the team manager should select for the 100m race.
