Step-by-step solution

Given information

The data for a randomly picked date showed the following annual goals as follows:

Western	Eastern
Los Angeles 9	D.C. United 9
FC Dallas 3	Chicago 8
Chivas USA 4	Columbus 7
Real Salt Lake 3	New England 6
Colorado 4	Metro Stars 5
San Jose 4	Kansas City 3

Explanation

When comparing Terry's race and practice lap times, it's clear that the mean time for practice laps is faster than the mean time for race laps.
Despite the fact that Terry drove more race laps $\left(20\right)$than practice laps $\left(15\right)$, her racing times are faster.
Assume that this occurred as a result of the adrenaline rush she experienced during the race, which she does not experience during her practice.
