To determine what happens to the mean when a 14-year-old player moves up to a different league, we need to consider how the mean age is calculated. The mean age (average) is found by summing the ages of all players and dividing by the number of players.
If a 14-year-old, who is above the current mean age of 12.2, leaves the team, the total age of the remaining players will decrease, and the number of players also decreases by one. Since the remaining players’ ages will now be less than the average age that included the 14-year-old, the new mean will be less than 12.2.
Thus, the response is:
**The mean decreases.**
