A new postsurgical treatment is being compared with a standard treatment. Seven subjects receive the new treatment, while seven others (the controls) receive the standard treatment. The recovery times, in days, are as follows: Treatment (X): 12 13 15 19 20 21 27 Control (Y): 18 23 24 30 32 35 40 Can you conclude that the mean rate differs between the treatment and control?
