Risk of home burglary in cul-de-sacs. Research published in the Journal of Quantitative Criminology (Mar. 2010) revealed that the risk of burglaries in homes located on culde-

sacs is lower than for homes on major roads. Suppose you want to estimate the true percentage of cul-de-sac homes in your home city that were burglarized in the past year. Devise a sampling plan so that your estimate will be accurate to within 2% of the true value using a confidence coefficient of 95%. How many cul-de-sac homes need to be sampled and what information do you need to collect for each sampled home?
