13. A recent sample of 20 individuals found that the average number of therapy sessions these persons required to recover from shoulder surgery was 9.6, with a standard deviation of 2.8. A separate sample of 25 individuals found that the average number of sessions these persons required to recover from hip surgery was 10.3, with a standard deviation of 2.3.
