A new postsurgical treatment was compared with a standard treatment. Eight subjects received the new treatment, while eight others (the controls) received the standard treatment. The recovery times, in days, are given below.

New Treatment Standard
12 18
13 23
15 24
19 30
20 32
21 35
24 39

Can you conclude that the mean recovery time for those receiving the new treatment differs from the mean for those receiving the standard treatment.
