Assume that a sample is used to estimate a population proportion
p. Find the margin of error
M.E.
that corresponds to a sample of size 331 with 34.1% successes at a confidence level of 95%.



M.E.
= %


Report answer accurate to one decimal place (as a number of percentage points).  Answer should be obtained without any preliminary rounding (however, the critical value may be rounded to 3 decimal places).
