rob sent an email survey to 2,000 cell phone owners asking about their satisfaction with their current plan. only 256 people returned the survey and they were predominately 18 - 24 years old. which of the following statements is true? rob included too many people on the survey list, affecting the data collected. rob is ignoring the assumption that all survey participants will want to act independently. the survey suffers from census issues because only 256 people responded. the survey likely has bias because the people who could not answer differ from those who did answer.
Answer
# Brief Explanations:
The low - response rate and the fact that respondents are predominantly from one age group suggest that those who answered may have different characteristics from non - respondents, indicating potential bias. Having a large survey list isn't inherently a problem. There's no indication of issues related to independent action. And this isn't a census issue as it's a sample survey.
# Answer:
The survey likely has bias because the people who could not answer differ from those who did answer.
