The ages of the members of four teams are summarized below. Answer the questions about them.
Team A: The range of ages is and the mean age is .
Team B: The range of ages is and the mean age is .
Team C: The range of ages is and the mean age is .
Team D: The range of ages is and the mean age is .
(a) Based on the information above, which team has the oldest members on average?
Team A
Team B
Team C
Team D
(b) Based on the information above, which team's ages have the most variability?
Team A
Team B
Team C
Team D
Since the range of ages for each team is not provided, we cannot determine which team has the oldest members on average.
To determine which team's ages have the most variability, we need to compare the ranges of ages for each team. Without the information on the range of ages for each team, we cannot determine which team has the most variability.
(a) To determine which team has the oldest members on average, you need to compare the mean ages of each team. So looking at the information given, you need to choose the team with the highest mean age.
(b) To determine which team's ages have the most variability, you need to look at the range of ages for each team. So looking at the information given, you need to choose the team with the highest range of ages.
