The ages of the members of four teams are summarized below. Answer the questions about them. Team A: The range of ages is 26 and the mean age is 47 . Team B: The range of ages is 22 and the mean age is 40 . Team C: The range of ages is 27 and the mean age is 43 . Team D: The range of ages is 18 and the mean age is 49 . (a) Based on the information above, which team has the youngest members on average? O Team B (b) Based on the information above, which team's ages have the most variability? O Team A Team B

**Step 1. Analyze the mean age for each team.** - For Team A, the mean age is \(47\). - For Team B, the mean age is \(40\). - For Team C, the mean age is \(43\). - For Team D, the mean age is \(49\). The youngest members on average belong to the team with the smallest mean age. Since \(40\) is the smallest value, the answer to part (a) is **Team B**. **Step 2. Analyze the variability of ages based on the range.** - For Team A, the range of ages is \(26\). - For Team B, the range of ages is \(22\). - For Team C, the range of ages is \(27\). - For Team D, the range of ages is \(18\). The most variability in ages corresponds to the largest range. Since \(27\) (Team C) is the largest range, the answer to part (b) is **Team C**.
