Probability challenge help

  1. Sep 17, 2006 #1
    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.:surprised

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

    Are you confused as to what ±.03 means?
