(а) A study is interested in the proportion of postgraduate students who have met the criteria of depression during their study periods. In a random sample of 50 postgraduate students, 15 are found to be afflicted. Use the normal distribution table to construct a 98% confidence interval for the proportion of postgraduate students who have experienced depression. What can we assert with 98% confidence about the possible size of our error if we estimate the proportion to be 0.30?
