Question

consider the survey descriptions shown. survey 1: a township employee surveys all 118 workers at a shopping mall to learn about the salaries of the workers. survey 2: a restaurant employee asks 40 repeat customers if they enjoy the food. survey 3: a company randomly selects 100 customers from its database and surveys them to see if they enjoy their product. complete the statements. survey is most likely to produce a representative sample. survey is most likely to produce a biased sample. survey collects information on an entire population.

Explanation:

• For a representative sample, random selection is ideal. Survey 3 randomly selects customers from a database, so it's most likely to produce a representative sample.
• A biased sample occurs when the selection process favors certain outcomes. Survey 2 asks only repeat - customers, who are more likely to enjoy the food, so it's most likely to produce a biased sample.
• Survey 1 surveys all 118 workers at a shopping mall, which means it collects information on an entire population (of workers at that mall).

Answer:

Survey 3 is most likely to produce a representative sample.
Survey 2 is most likely to produce a biased sample.
Survey 1 collects information on an entire population.
