They conducted a variety of face to face and phone interviews with youth during their survey.

Complete parts (a) and (b) below. What kinds of bias might they be referring to? Select all suitable answers below. A. There may be nonresponse bias in an attempt to mislead the questioner. B. There may be nonresponse bias based on the type of people willing to agree to the interview. C. There may be response bias in an attempt to please the questioner. D. There may be response bias based on the wording of the question. (b) Does their margin of error suggest that this was a simple random sample? Explain. A. Yes, the data suggest that this was a simple random sample. B. No, the margin of error from a simple random sample at 99% confidence would be _ which is significantly less than the given margin of error. It is likely that a more complicated sampling method was employed. C. No, the margin of error from a simple random sample at 99% confidence would be _ which is significantly more than the given margin of error. It is likely that a more complicated sampling method was employed.
