# Calculating A Confidence Interval for a Proportion II

In your study you found that a proportion `p`

of 0.35 of your sample said they have road rage. The standard error of this proportion is found through square root of: p multiplied by 1 - p, divided by n. Let's try this!

Instructions

**100 XP**

- Add a line of code that calculates the standard error of p, and stores this as
`se`

- Remember to format your calculations correctly and use
`()`

where appropriate - If you want to take a look at your dataset, it is still saved in your console as
`roadrage`
