Question

The sale of eggs that are contaminated with salmonella can cause food poisoning among consumers. A large egg producer takes a SRS of 200 eggs from all the eggs shipped in one day. The laboratory reports that 11 of these eggs had salmonella contamination. Unknown to the producer, 0.2% (two-tenths of one percent) of all eggs shipped had salmonella. In this situation: A) 0.2% is a parameter and 5.5% is a statistic. B) 5.5% is a parameter and 0.2% is a statistic. C) both 0.2% and 5.5% are statistics. D) both 0.2% and 5.5% are parameters. E) 0.2% is a parameter and 5.5% is unrelated to the problem.

Answer 1

A) 0.2% is a parameter and 5.5% is a statistic.

Explanation:

0.2% is a parameter because it is a characteristic of the population. It describes all eggs shipped.

5.5% is a statistic because it describes a sample and not the full population of eggs shipped.
