<h3>How to Identify the source of Bias?</h3>
The source of bias that affected the confidence interval, but is not included among the sources covered by the margin of error is; Under coverage Bias
The reason why I picked under coverage bias is because we see from the survey that they send a survey home with a random sample of students in the district. However, when the survey was not completed, calls are made to ensure responses are obtained from the parents of every selected student. Then the question is changed again.
Thus, it is clear that not all was captured and that is why we go with under coverage bias.
