## Mean..SD

Theres a wrestling team.

5 wrestlers.

Each of them have a different weight class, and for each wrestler, it has the mean differentials(difference in points between these wrestlers and their opponents) and the SD for the first 10 meets.

a) suppose the team score is calculated directly from the point differentials. What would the mean score and SD for this team be?

b) Team scores are not calculated directly from the point differentials. If the real team score average for last season was 39.5 with a SD of 13.202, do you have any reservations about using this info and part(a) to determine if there is a significant difference in the two scoring methods?
