Question

analyzing sampling 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 \\(\boldsymbol{\square}\\) is most likely to produce a representative sample. survey \\(\boldsymbol{\square}\\) is most likely to produce a biased sample. survey \\(\boldsymbol{\square}\\) collects information on an entire populat

Explanation:

1. A representative sample uses random selection to reflect the whole population. Survey 3 randomly selects customers, so it is representative.
2. A biased sample favors a specific group. Survey 2 only asks repeat customers (a group already likely to enjoy the food), so it is biased.
3. Survey 1 surveys all 118 workers, which is the entire target population, so it collects data on the whole group.

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.
