Use the "plus four" method to estimate the 95% confidence interval for the population proportion of single-floor homes in the area. Remember, you must calculate p', q', and Zo 025 in order to determine your error bound of the population proportion (EBP). Write a sentence that interprets the estimate in the context of the situation in the problem. nclude the confidence level and confidence interval. (Use the statement below as a template.) "We believe, at the % confidence level, that the true population proportion of single-floor homes in Winston-Salem lies between % and %."
