Question

A company is trying to determine if they should accept a shipment of toy parts. The shipment has over 1 million parts. They decided to randomly select 100 parts out of the shipment. They will only accept the shipment if 1% or less of all of the parts are defective. Out of the 100 selected, 4% are defective. Identify the numbers "1%" and "4%" as either statistics or parameters. Group of answer choices

Answer 1

4% is a statistic and 1% is a parameter

Explanation:

First, let's remember the differences between parameters and statistics:

Parameters are values that describe data of the entire population.

Statistics are values that describe data from a sample.

The value of 1% refers to "all of the parts", which is the population of over 1 million parts, thus 1% is a parameter.

The value of 4% refers to the "100 selected", which is the sample of 100 parts, thus 4% is a statistic.

Therefore, 4% is a statistic and 1% is a parameter.
