- (b) Team D has the youngest members on average.
Solución
To answer the questions, we need to analyze the information provided about the teams’ ages, specifically focusing on the range and mean age.
Given Information:
- Team A: Range = 17, Mean Age = 41
- Team B: Range = 23, Mean Age = 39
- Team C: Range = 19, Mean Age = 43
- Team D: Range = 20, Mean Age = 34
(a) Which team’s ages have the most variability?
The variability of ages can be assessed using the range. A larger range indicates more variability in ages.
- Team A: Range = 17
- Team B: Range = 23
- Team C: Range = 19
- Team D: Range = 20
Conclusion for (a): Team B has the largest range (23), indicating that it has the most variability in ages.
(b) Which team has the youngest members on average?
To determine which team has the youngest average age, we can compare the mean ages directly.
- Team A: Mean Age = 41
- Team B: Mean Age = 39
- Team C: Mean Age = 43
- Team D: Mean Age = 34
Conclusion for (b): Team D has the youngest average age (34).
Final Answers:
- (a) Team B
- (b) Team D

The team with the most variability in ages can be determined by analyzing the range of ages. Team B has the largest range of 23 years, indicating the greatest variability among its members. So, for (a), the correct choice is Team B.
As for which team has the youngest members on average, we look at the mean ages. Team D has a mean age of 34, which is younger than the mean ages of Teams A (41), B (39), or C (43). Hence, for (b), the correct choice is Team D.
