In a study on the healing process of a cut, researchers observed the time required to completely heal the cut. 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 hours) to completely heal the cut for each rat is given below. Control: 23, 27, 30, 26, 31Treatment: 21, 22, 18, 24, 30 Test if the mean duration of healing can be reduced by the medical treatment What is the value of the test statistic (round off to second decimal place)
