Two delivery drivers last month:
Driver 1: 800 deliveries, 16 late
Driver 2: 500 deliveries, 5 late
A manager claims that Driver 2 was more punctual than Driver 1. Which choice most effectively uses data from the table to support the claim?
- A. Driver 2 was late on 1% of deliveries (5 of 500), compared with 2% for Driver 1 (16 of 800).Correct
- B. Driver 1 made more deliveries than Driver 2.
- C. Driver 2 had fewer late deliveries than Driver 1.
- D. Driver 1 had 16 late deliveries.
Answer: A. Driver 2 was late on 1% of deliveries (5 of 500), compared with 2% for Driver 1 (16 of 800).
Punctuality is a rate; choice A computes both.
Why the other answers are wrong
- B. Driver 1 made more deliveries than Driver 2.
- Volume, not punctuality.
- C. Driver 2 had fewer late deliveries than Driver 1.
- Fewer late deliveries could just mean fewer deliveries; the rate is needed.
- D. Driver 1 had 16 late deliveries.
- One figure, no comparison.
