Answer
Brief Explanations:
To get a representative view of all customers, a random - sampling approach is best. Asking every 10th customer is a form of systematic random sampling which gives a broader range of opinions compared to sampling based on gender or specific age - groups only. Sampling based on gender or specific age - groups may introduce bias as it doesn't represent the entire customer base.
Answer:
Asking every 10th customer what they think about the new brand of coffee.
