Fidelity would like to estimate the proportion of privately
traded companies that automatically enroll their employees in a
401k retirement plan. Assume that the desired margin of error is
0.03 for a 95% confidence interval.
How large a sample should be selected if no planning value for
the proportion could be specified?
