Information and Ideas practice question

Two farms' egg production last week: Farm P: 180 hens, 900 eggs Farm Q: 120 hens, 720 eggs

A farmer claims that Farm Q's hens laid more eggs per hen than Farm P's. Which choice most effectively uses data from the table to support the claim?

  1. A. Farm Q's hens laid 6 eggs each (720 ÷ 120), compared with 5 each at Farm P (900 ÷ 180).Correct
  2. B. Farm P produced more eggs than Farm Q.
  3. C. Farm Q has fewer hens than Farm P.
  4. D. Farm Q produced 720 eggs.

Answer: A. Farm Q's hens laid 6 eggs each (720 ÷ 120), compared with 5 each at Farm P (900 ÷ 180).

Per hen requires dividing eggs by hens for both farms.

Why the other answers are wrong

B. Farm P produced more eggs than Farm Q.
Totals point the other way and ignore flock size.
C. Farm Q has fewer hens than Farm P.
Flock size alone says nothing about eggs per hen.
D. Farm Q produced 720 eggs.
A count without a rate.
