Question

the ages of the members of four teams are summarized below. answer the questions about them. team a: the mean age is 44 and the range of ages is 18. team b: the mean age is 47 and the range of ages is 17. team c: the mean age is 38 and the range of ages is 16. team d: the mean age is 45 and the range of ages is 11. (a) based on the information above, which team has the youngest members on average? team a team b team c team d (b) based on the information above, which teams ages have the least variability? team a team b team c team d

Explanation:

Step1: Compare mean ages for (a)

Compare 44, 47, 38, 45. 38 (Team C) is the smallest, so Team C has the youngest - members on average.

Step2: Compare ranges for (b)

Compare 18, 17, 16, 11. 11 (Team D) is the smallest. Since range measures variability, Team D has the least variability in ages.

Answer:

(a) Team C
(b) Team D
