To estimate the percentage of a species of rodent that carries a specific viral infection, 125 rodents are randomly selected and examined, and 65 of them are found to be infected. Based upon this, find a 99% confidence interval for the proportion of all rodents of this species that are infected with the virus. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places. (If necessary, consult a list of formulas.) What is the lower limit of the  99%  confidence interval?   What is the upper limit of the  99%  confidence interval?
