1. A professional sports team evaluates potential players for a certain position based on two main characteristics, speed and strength.
(a) Speed is measured by the time required to run a distance of 40 yards, with smaller times indicating
more desirable (faster) speeds. From previous speed data for all players in this position, the times to run
40 yards have a mean of 4.60 seconds and a standard deviation of 0.15 seconds, with a minimum time of
4.40 seconds, as shown in the table below.

Standard Deviation
Minimum
4.40 seconds
Time to run 40 yards 4.60 seconds
