How could the central limit theorem be used to gauge the probable size of the error of the estimate of the previous problem? Denoting the estimate by \(\hat{A}\), if A = .2, how large should n be so that \(P(|\hat{A}-A|<.01) \approx .99\)?

QUESTION:
How could the central limit theorem be used to gauge the probable size of the error of the estimate of the previous problem? Denoting the estimate by \(\hat{A}\), if A = .2, how large should n be so that \(P(|\hat{A}-A|<.01) \approx .99\)?
ANSWER:Step 1 of 5
Let \(\varepsilon>0\) be arbitrary value, so that we need to find \(P(|\hat{A}-A|<\varepsilon)\)
Where A is the area of a region of unknown size, and \(\hat{A}\) is its estimate.
The estimate \(\hat{A}\) was defined as follows:
Let \(Z_{1}, Z_{2}, \ldots, Z_{n}\) be independent identically distributed random variables such that
\(Z_{i}=\left\{\begin{array}{ll} 1, & (X, Y) \in R \\ 0, & (X, Y) \notin R \end{array}\right.\)
