Suppose that administrators at a large urban high school want to gain a better understanding of the prevalence of bullying within their school. they select a random sample of 200 students who are asked to complete a survey anonymously. of these students, 63 report that they have experienced bullying. use this information to find a 90% z-confidence interval for p, the true proportion of students at this school who have experienced bullying. give the limits (bounds) of the confidence interval as a proportion, precise to three decimal places.
