A sociologist is studying the prevalence of crime in one major city. In a sample of 200 randomly selected residents, 58 say that they have been victimized by a criminal. Based on this sample, construct a 99% confidence interval for the proportion of all residents in this city who have been victimized by a criminal. Then find the lower limit and upper limit of the 99% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places. (If necessary, consult a list of formulas.) Lower limit: Upper limit: X 3
