Question
What do the computed mean and median tell you? Fill in the blanks below. (Use a 25% difference as the criterion for a "substantial" difference between the mean and median.) The prediction was because the mean the median in this distribution. (e) Determine the mode. The mode is (Type an integer or decimal rounded to two decimal places as needed.) (f) Do you believe that the survey suffers from bias? If so, what type and why? O A. Yes, the survey suffers from sampling bias because the number of male and female students surveyed was the same. B. No, the survey does not suffer from bias because it was administered randomly and the question asked is in balanced form. O C. Yes, the survey suffers from response bias because it would be difficult to achieve truthful responses to this type of question unless the identity of the respondents is anonymous. O D. Yes, the survey suffers from sampling bias because the number of male and female students surveyed was not the same.
