Question: In the past, the percent of smokers able to quit smoking "cold turkey" was reported to be no more than 0.10. If we wished to make a new estimate of that percent that now were able to quit "cold turkey" with a precision (margin of error) of plus and minus 0.02 and with 99% confidence, how large a sample would be required? What sample size would be required to make that estimate within plus and minus 0.03 and with 95% confidence?
