Using sampling concepts, it is found that the correct option is given by:
D. Move-Em-Out because the sample is not biased.
<h3>What is sampling?</h3>
It is when a group is taken from a population, and the data taken from the group can be taken to estimate the data for the entire population. A sample has to be representative of the population, that is, it has to avoid bias.
In this problem, the sample from Pack-and-Move was taken only from people who appeared in their commercials, meaning that the sample is biased, as these people are more likely to report high satisfaction, hence option D is correct.
