Georgia [21]
Standard deviation= σ= 0.1 
Confidence interval= 95%= 0.95
Significance level=α= 1-0.95= 0.05
 α/2 = 0.025
At  α/2  z( α/2 ) =1.960   [from statistic table]
Now,
the sample size at error of 0.02 is
0.02=z( α/2 )σ/√n
0.02=(1.960)*(0.1)/√n
5/49 = 1/√n
√n=49/5
n=96.04
n should be 96 or greater
