1. Researchers think that people who are physically fit have a higher self-esteem than those who are not fit. They divided people into two groups - low fitness and high fitness - and measured their ESP - ego, strength, and personality. Their ESP scores are:

Low Fitness	High Fitness
4.93	4.99	6.72	6.53
4.75	5.12	5.53	5.15
4.66	4.46	6.06	5.82
5.09	4.83	6.21	5.71
5.25	4.92	5.98	5.09
4.73	5.06	5.12	5.46
6.00		6.37	5.22
5.15		4.99	5.69

Is there a significant difference in ESP at the 5% level? Is there a difference at the 1% level. State your conclusions in the proper form.
