Question

Select the scenario which is an example of simple random sampling.

A) Surveying every third person entering a shopping mall.
B) Surveying the first 100 people who enter a grocery store.
C) Surveying only people who agree to participate in a study.
D) Surveying everyone who works in a specific company.

Answer 1

The true example of simple random sampling is not clearly outlined in the options given, but based on the additional information, the correct example is when a computer generates random numbers to select individuals, ensuring equal selection chance. Option D is correct.

Step-by-step explanation:

The scenario which is an example of simple random sampling is D) Surveying everyone who works in a specific company. However, upon reviewing the options and additional information provided, this is actually incorrect. The correct answer wasn't clearly provided in the options, but based on the reference information, the scenario that best matches simple random sampling would be scenario 17.

A computer generates 100 random numbers, and 100 people whose names correspond with the numbers on the list are chosen. This is because, in a simple random sample, each member of the population has an equal chance of being selected.

In scenario 17, the use of a computer to generate random numbers ensures that there is no bias in the choice of subjects, as opposed to the other options which are examples of systematic (A), convenience (B), and voluntary response (C) sampling techniques, respectively.
