To estimate the percentage of a species of rodent that carries a specific viral infection, 125 rodents are randomly selected and examined, and 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 th the lower limit and upper limit of the 90% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places. (If necessary, consult a Lower limit: Upper limit:

Question
### Estimating the Proportion of Infected Rodents

To estimate the percentage of a species of rodent that carries a specific viral infection, 125 rodents are randomly selected and examined, and 67 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. Then find the lower limit and upper limit of the 90% 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.)

1. Enter the Lower limit: [              ]
2. Enter the Upper limit: [              ]

There are action buttons for computations as follows:
- One button with an 'X' symbol, likely meant for clearing the entered data.
- One button with a circular arrow, likely used for resetting the data entry.
- One button with a 'Question mark' symbol, likely to provide help or additional information.

##### Instructions:
- Carry your intermediate computations accurately to at least three decimal places.
- Round your final answers to two decimal places for precision.

This exercise aims to help students understand how to calculate confidence intervals for proportion estimates in a real-world context using a practical example.
