A sociologist is studying the prevalence of crime in one major city. In a sample of 225 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.  Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places.    (a)  What is the lower limit of the 99% confidence interval?   (b)  What is the upper limit of the 99% confidence interval?
