To estimate the percentage of a species of rodent that carries a specific viral infection, 200 rodents are randomly selected and examined, and 102 of them are found to be infected. Based upon this, find a 90% confidence interval for the proportion of all rodents of this species that are infected with the virus.
- Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places.
- What is the lower limit of the 90% confident interval?
- What is the upper limit of the 90% confident interval?
