In the fall semester of 2003, the average graduate management admission test (GMAT) of the students at UTC was 500 with a standard deviation of 80. in the fall of 2004, the average GMAT was 560 with a standard deviation of 84. which year's GMAT scores show a more dispersed distribution

The 2003 scores have a higher coefficient of variation, so they are more dispersed

Step-by-step explanation:

We have to find the coefficient of variation(CV) for both these tests.

In which is the mean and is the standard deviation.

Whoever has the higher CV has the higher variation, that is, is more dispersed.

2004

The 2003 scores have a higher coefficient of variation, so they are more dispersed.
