Hospital H conducted a survey of two groups of patients who were enrolled in an exercise rehabilitation program last month. Was the range of the numbers of days that the patients in the first group exercised last month equal to the range of the numbers of days that the patients in the second group exercised last month?

(1) For each group, the number of patients enrolled was 21 and the least number of days that a patient exercised last month was 5.

(2) For each group, the average (arithmetic mean) number of days that the patients exercised last month was 13.
