Homework Help: [Question]How to find lower bound for this exercise

  1. May 30, 2015 #1
    1. The problem statement, all variables and given/known data

    Apply the Central limit theorem to evaluate approximately the lower bound for the probability that the difference between the relative frequency p^ and p is less than 0.01, if n = 4500
    2. Relevant equations

    This exercise do not give me the confidence interval? What function can help me solve this problem
    3. The attempt at a solution
    I think in this problem, i will choose random p^, p and the different between them is 0.01 => find approximately Za/2 => i have lower bound

    It would be a good idea to start by stating the "central limit theorem". That might give you some ideas.
