Hi, I have no idea of this ±.03 :cry:

A population proportion is .40. A simple random sample of size 200 will be taken and the sample proportion 'p' will be used to estimate the population proportion.

a. what is the probability that the sample proportion will be within ±.03 of the population proportion?

Are you confused as to what ±.03 means?
