Alvin Wiggins · Answer 1

E) Random

Explanation:

Random sampling technique will be employed in surveying all customers present because there is no preconceived condition. Also, it presents an equal probability of each customer being chosen. It is an unbiased representation of the total number of their customers.

Stephen Archer · Answer 2

E. Cluster

Explanation:

Cluster sampling is a type of sampling method in which the population under study is divided into different groups known as clusters before simple random samples are selected from each population clusters. The analysis of such population is carried out based on the sampled clusters.

This method is adopted when a researcher does not have access to the whole population under research.

Advantages of cluster sampling.

The research method only needs fewer resources.

The sample under review is feasible.

Note: Cluster sampling is not as accurate as simple or stratified random sampling.
