The ages of the members of four teams are summarized below. Answer the questions about them. Team A: The mean age is 29 and the range of ages is 30 . Team B: The mean age is 32 and the range of ages is 24 . Team C: The mean age is 31 and the range of ages is 25 . Team D: The mean age is 38 and the range of ages is 27 . (a) Based on the information above, which team has the oldest members on average? (b) Team A Teased on the information above, which team's ages have the least variability? O Team A Team B

Let's analyze the information provided for each team to answer the questions: ### (a) **Which team has the oldest members on average?** To determine which team has the oldest members on average, we look at the **mean age** of each team: - **Team A:** 29 years - **Team B:** 32 years - **Team C:** 31 years - **Team D:** **38 years** **Answer:** **Team D** has the oldest members on average with a mean age of 38 years. ### (b) **Which team's ages have the least variability?** Variability in ages can be assessed by looking at the **range** (the difference between the oldest and youngest members). A smaller range indicates less variability in ages. - **Team A:** Range of 30 years - **Team B:** Range of 24 years - **Team C:** Range of 25 years - **Team D:** Range of 27 years **Answer:** **Team B** has the least variability in ages with a range of 24 years.
