Eg would be 10.6 because its the same length as EF
 
        
                    
             
        
        
        
The margin of error of the random selection is 0.20
The given parameters are:
 --- the sample size
 --- the sample size
 --- the standard deviation
 --- the standard deviation
 --- the mean
 --- the mean
 --- the confidence level.
 --- 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
