At a popular hamburger restaurant, the manager checks the quality of the burgers every 20 minutes, starting at a randomly selected time.

Step-by-Step Solution

Answer

The sample is burgers which are checked.

The population is all burgers.

The sample is systematic random samples.

Step 1. Identify each sample, and suggest a population from which it was selected.

A sample is some portion of a larger group called the population.

Therefore, the sample is burgers which are checked and the population is all burgers.

Step 2. Classify the type of sample.

Systematic random sample is a sample in which the items in the sample are selected according to a specified time or item interval.

As, quality of the burgers are checked after every 20 minutes. That is sample is selected according to a specified time. Therefore, the sample is systematic random samples.
