A clinical trial is run to test the effects of different forms of regular exercise on HDL levels in persons between the ages of 18 and 29 years. Participants in the study are randomly assigned to one of the three exercise groups. There are three exercises: Weight training, Aerobic exercise, or Stretching/Yoga. Their HDL levels are measured after 8 weeks are shown in the below table.

Exercise Group	N	Mean	Std Dev
Weight Training	12	48.0	12.0
Aerobic Exercise	12	56.1	14.2
Stretching\Yoga	12	44.0	13.5

running the test at a=0.05 is there a significant difference in mean HDL levels among the exercise groups? If the test statistic is statistically significant, you must indicate its p-value. Hint: SSerror= 5807
