Using the given margin oferror, confidencelevel, and likely range for the observed value of the sampleproportion, obtain a sample size that will ensure a margin of error of at most the one specified(provided, ofcourse, that the observed value of the sample proportion is further from 0.5 than the educatedguess).

margin of error=0.01; confidence level=95%; likely range=0.15 to .35

The required sample size is n = _____
