Question

The table shows summary statistics for guests' ages at two parties.

Party Median age (years) Range (years)
1 17 27
2 19 20
Which conclusion is true?


A. A typical guest at Party 1 was younger than a typical guest at Party 2, and guests' ages were more variable at Party 1 than at Party 2.

B. A typical guest at Party 1 was younger than a typical guest at Party 2, and guests' ages were less variable at Party 1 than at Party 2.

C. A typical guest at Party 1 was older than a typical guest at Party 2, and guests' ages were more variable at Party 1 than at Party 2.

D. A typical guest at Party 1 was older than a typical guest at Party 2, and guests' ages were less variable at Party 1 than at Party 2.

Answer 1

The answer is A... A typical guest at Party 1 was younger than a typical guest at Party 2, and guests' ages were more variable at Party 1 than at Party 2.

Answer 2

median age of 1 is 17, median age of 2 is 19 so the average age of party 1 is younger

the range of 1 is 27, the range of 2 is 20 so the range of 1 is larger, which means there is more variance
the answer should be

A. A typical guest at Party 1 was younger than a typical guest at Party 2, and guests' ages were more variable at Party 1 than at Party 2.
