Item 2 Exc. 2

An experiment to determine if physical fitness has any effect on a person's alertness was conducted. People were classified as being in one of five possible physical fitness populations: (1) non-fit, (2) minimal, (3) average, (4) above average and (5) excellent.

Random samples from each population were taken and an alertness test was given to each person. The results are shown below.

Level of Physical Fitness

Non-Fit	Minimal	Average	Above Average	Excelent
6.7	7.2	4.7	6.1	5.6
3.7	4.5	6.2	5.0	6.3
4.8	3.6	8.3	7.1	7.9
3.0	3.5	5.5	7.8	6.4
4.8	8.2	6.1	4.4	8.6
1.9	5.0	3.1	6.0	9.3
4.7		7.2	9.0	8.6
5.9		6.3	5.9
3.7		4.0
		7.2

At the 0.01 level of significance, test to see if there are any differences between the mean alertness score among the different levels of physical fitness populations.
