The margin of error of the random selection is 0.20
The given parameters are:
--- the sample size
--- the standard deviation
--- the mean
--- the confidence level.
The margin of error (E) is calculated as follows:

So, we have:


The z-value for 99% confidence level is 2.576.
Substitute 2.576 for z


Take square roots

Multiply

Approximate

Hence, the margin of error is 0.20
