there is a difference in the mean duration of recovery
An orthopedic surgeon wanted to know the effectiveness of three suture techniques on tendon repair of injured athletes. Specifically, he wanted to see if there is a difference in the mean duration of recovery (in weeks) for the said volunteers who were introduced to these methods. At 95% confidence level, test the hypothesis that there is a difference among the means by using the p-value method of hypothesis testing.
