Question

Mr. Dotson wants to know if the neighbors on his street would be interested in a community watch. He surveys every fourth household and concluded that 70% would be interested

Answer 1

The answer is "This is true since it is a random systematic sample".

Explanation:

In the given scenario, Systemic random sampling involves the random sampling method which often involves the collection of samples onto an interval system in such a numbered group of people based on the premise/base. It also is a selection of samples at a particular preset interval.

• Calculate the sampling interval and fix it quickly. (The sample population divided with several selected components needed).
• Take a random value between 1 to a sample interval.
• Replicate the sample size to choosing all additional sections.
