consider the following sample statistics from a population that is aproximatly normal. n=15, s= 7.92,level of confidence is 99 %
Calculate the margin of error( round to the nearest hunderth)

statistics 
MathGuru,
Margin of error = + or  (zvalue)(s/√n)
...where zvalue is found using a ztable for 99% confidence, s = standard deviation, and n = sample size.
Look up the value in the table, then substitute what you know into the formula.
I hope this will help get you started.
