Information and Ideas practice question

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?

  1. A. Driver 2 was late on 1% of deliveries (5 of 500), compared with 2% for Driver 1 (16 of 800).Correct
  2. B. Driver 1 made more deliveries than Driver 2.
  3. C. Driver 2 had fewer late deliveries than Driver 1.
  4. 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.
