In a study designed to compare fasting blood sugar readings for 3 groups of diabetic patients, one group used insulin to control the problem, one group used oral drugs and another group used diet and exercise. The blood sugar readings for the three samples are shown below. Conduct an ANOVA test to determine if there is a difference in the three different treatments effect to blood sugar (Ho: Blood sugar means are equivalent, Ha: At least one of the means is different). Conduct this test at alpha equal .05.

Insulin Oral Drug Diet/Exercise
