Answer 1

Option B) It is flawed because it is a voluntary response sample

Explanation:

We are given the following situation in the question:

" In a survey of 568 ​subjects, each was asked how often he or she ate bananas. The survey subjects were internet users who responded to a question that was posted on a news website."

This a flawed survey.

Voluntary response sample:

• In this sampling the subject decides whether to be a part of the sample or not.
• Thus, with respect to the above situation the internet user may choose to participate in the given survey or not.
• These samples are biased samples.
• This sample is likely to have biased people: against the topic or in support of the topic.
• the people choose themselves to be a part of sample or not, hence highly biased.

Option B) It is flawed because it is a voluntary response sample
