identify the sampling techniques used, and discuss potential sources of bias (if any). explain. choose at random, 530 customers at a grocery store are contacted and asked their opinions of the service they received. what potential sources of bias are present, if any? select all that apply. a. the sample consists only of customers that are easy to reach. this sample may not be representative of the population. b. the wording of the question asked to the customers may influence them towards a particular response. the results would not be usable in this case. c. if there is a regular pattern to the customers, it is possible for the sample to not be representative. d. there are no potential sources of bias.
Answer
# Brief Explanations:
The sampling technique is random selection of 50 customers at the grocery store. Potential bias: The sample consists of customers present (easy to reach), which may not represent all customers (e.g., those who shop at different times or online), making it unrepresentative. Wording bias (B) isn't indicated, regular patterns (C) don't affect random sampling, and there is a potential bias (so D is incorrect).
# Answer:
A. The sample consists only of customers that are easy to reach. This sample may not be representative of the population.
