    So my teacher is really confusing me for higher level leaving cert maths and he just can't answer this question: When I'm looking for the percentage error do I use the 1/the square root on n. He says that it may be a different formula this year but won't say what it is. Thanks.

    1/rootN isn't used anymore because it's inaccurate/ only 95% confidence.

    the new formula is +-1.96(sigma/sqrtn) You should read that anyway.
