Step-by-step explanation:

From the information given;

The population is the pet store customers. A population in statistics encompasses a set of similar items or events which are of interest for some question or experiment and from which a sample can be obtained.

The sample is the 100 customers surveyed by the pet store owner. A sample is basically is a subset of the entire population. From the population of pet store customers we sample 100 customers for survey.

This sample is likely to be biased since not all customers have dogs. Considering a pet store, some customers might be having cats. These customers will have no idea of what brand of dog food is purchased most frequently
