[Question]How to find lower bound for this exercise

[cuongbui1702]

Homework Statement

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

Homework Equations

This exercise do not give me the confidence interval? What function can help me solve this problem

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.
