Answer
# Brief Explanations:
Non - response bias occurs when some members of the population cannot be contacted or refuse to answer the survey, leading to a sample that is not representative of the population. Having too few subjects is sample size issue, not non - response bias. Subjects not answering every question is item non - response, not the overall non - response bias. Subjects not being representative due to some being unable to complete a survey is more about access issues rather than the typical non - response bias of non - contact or refusal.
# Answer:
The subjects in the study are not representative of the population, because some members of the population could not be contacted or refused to answer the survey.
