Question

Quizplus · Accepted Answer

Since the sample size is large enough (n=2800) and the results are dichotomous (yes or no), a 99% confidence interval can be calculated. However, there is still a possibility that the interval will not contain the true proportion of the student population who feel comfortable reporting cheating. This is because the sample may not fully represent the population and there is always some degree of sampling error.
