You work for the BC Lottery Corp. Your boss asks you for an estimate of the percent of British Columbians who have gambled in a BC casino at least once. You decide to take a sample large enough so that the margin of error is no larger than 6% with 95% confidence. Before you take the sample you have no idea what percent have gambled in a BC casino. The results of your sample indicate that 80% have gambled in a BC casino at least once. Your boss tells you the margin of error is too large and wants it reduced to 3%. How many additional adults would you need in your sample to reduce the error to 3%?
