Answer & Explanation

Correct answer

1: No · 2: Yes · 3: Yes

Each statement is a relationship across the table, not a single number you can point to.

Statement 1 - No. The range of weekly sales is the largest minus the smallest: $80K (Cedar) − $38K (Dale) = $42K. That is not more than $50K, so the statement is false. The trap is to read the range as the top value, $80K, which clears $50K - but a range is a spread, max minus min, not the maximum itself.

Statement 2 - Yes. The three lowest-selling stores are Dale ($38K), Birch ($45K), and Elm ($52K); together that is $135K. Cedar alone posts $80K. Since $135K is more than $80K, the statement is true. The pull is to assume the top store towers over the rest, so its single figure feels bigger than three 'small' stores combined; but three mid-size stores easily out-total it.

Statement 3 - Yes. Order the stores by weekly sales from highest to lowest: Cedar, Aspen, Elm, Birch, Dale. Their staff counts in that order are 30, 24, 21, 18, 15 - strictly decreasing - so the same ranking does list staff from highest to lowest, and the statement is true. The trap is to assume two different measures need not move together and answer No without checking; here they happen to line up perfectly.

The through-line: a range is a spread, several mid-size values can outweigh one large one, and whether two columns rank in the same order has to be checked, not assumed. Correct answers: No / Yes / Yes.
