A homogeneous powder, derived from a sample of Ayre's Rock in Australia, is known to contain 33.31% Fe. The titration method used in your lab for Fe determinations is known to have a standard deviation of 0.27% Fe. Assuming you incur NO determinate errors, a single titration of such a sample would be expected, with 95.5% certainty, to fall in the range of X% to Y%, where X is less than Y. What is the numerical value of X?
