Explanation:

Systematic random sampling involves selecting every nth individual from a population. Here, the manager surveys every 20th person entering the store, which fits the definition of systematic random sampling. Simple random sampling would involve randomly selecting individuals without a fixed interval, stratified sampling divides the population into groups and samples from each, and cluster sampling divides into clusters and samples entire clusters. So the correct type is systematic random sampling.

Systematic random sampling
