In a study on the healing process of bone fractures, researchers observed the time required to completely heal a bone fracture. Ten rats were randomly divided into two groups of five. No treatment was done to one group and a medical treatment was given to the other group. The time spent (in days) to completely heal the fracture for each rat is given below. Control: 30, 22, 28, 35, 45 Treatment: 33, 40, 24, 25, 24 Test if the mean duration of healing can be reduced by the medical treatment at alpha = 0.1. Assume equal variance.
