Answer:
A. People who were promised free samples of Penelope's Puffy Popcorn for completing the survey.
Step-by-step explanation:
We are given that,
Out of 6000 people, 95% preferred Puffy Popcorn over any other brand.
It is required to find the group of people who were most likely surveyed.
Now, as we see that,
Number of people who prefer Puffy Popcorn = 95% of 6000 = 5700
Number of people who do not prefer Puffy Popcorn = 6000 - 5700 = 300
So, we get that,
Majority of the people out of the group prefers the Puffy Popcorn.
That is, the result is most likely to be a biased result.
According to the options, the group most likely to be surveyed is,
A. People who were promised free samples of Penelope's Puffy Popcorn for completing the survey.
