The ages of the members of four teams are summarized below. Answer the questions about them. Team A: The range of ages is 23 and the mean age is 43 . Team B: The range of ages is 27 and the mean age is 44 . Team C: The range of ages is 21 and the mean age is 41 . Team D: The range of ages is 20 and the mean age is 46 . (a) Based on the information above, which team's ages have the most variability? Team A Team B Team C Team D (b) Based on the information above, which team has the oldest members on average? Team A Team B Team C Team D

Find Team Variability: To find the team with the most variability, we look at the range of ages. The team with the highest range has the most variability. Team A range: 23 Team B range: 27 Team C range: 21 Team D range: 20Team with Most Variability: Team B has the highest range of 27, so it has the most variability.Find Team Average Age: To find the team with the oldest members on average, we look at the mean age of each team. Team A mean age: 43 Team B mean age: 44 Team C mean age: 41 Team D mean age: 46Team with Oldest Members: Team D has the highest mean age of 46, so it has the oldest members on average.

Find Team Variability: To find the team with the most variability, we look at the range of ages. The team with the highest range has the most variability. $\newline$ Team A range: $23$ $\newline$ Team B range: $27$ $\newline$ Team C range: $21$ $\newline$ Team D range: $20$
Team with Most Variability: Team B has the highest range of $27$ , so it has the most variability.
Find Team Average Age: To find the team with the oldest members on average, we look at the mean age of each team. $\newline$ Team A mean age: $43$ $\newline$ Team B mean age: $44$ $\newline$ Team C mean age: $41$ $\newline$ Team D mean age: $46$
Team with Oldest Members: Team D has the highest mean age of $46$ , so it has the oldest members on average.
