Six infants were involved in a study to compare the effectiveness of two medications for the treatment of diaper rash. For each baby two areas of approximately the same size and rash severity were selected and an area was treated with medication A and the other with medication B. The number of hours for the rash to disappear was recorded for each medication and each infant and the values obtained are given below:

Infant	1	2	3	4	5	6
Medication A	46	50	46	51	43	45
Medication B	43	49	48	47	40	40

At the significance level 0.01 is there sufficient evidence to conclude that a difference exists in the mean time required for the elimination of the rash?
