the population is 34,000. the sample is 256

Explanation:

The population is the entire group of interest. Here, it's all 34,000 customers who made debit - card purchases. The sample is the subset of the population that is actually studied. In this case, 256 people who responded to the survey are the sample. The 2,000 people who received the survey are just a subset of the population from which the sample (respondents) was drawn.
