A podiatrist recorded the recovery time, in days, for 38 patients. He was trying out a new procedure and hoped the result would be less recovery time on average. The mean recovery using the previous procedure was 6.5 days. The recorded times were:

8	7	8	6	9	4	5	3	7	8	10	7	7	6	4	10	3	6	8
2	5	5	4	5	3	8	7	4	6	3	7	12	4	3	6	6	9	4

Note that Σx = 229 and Σx² = 1581.
