In the Star and Tribune newspaper, there is an article entitled "1 in 8 school buses fail tests." Thearticle says that the overall statewide proportion of school buses that fail safety tests is 9%.However, one bus company has a higher rate of over 12%. Assume that we want a new estimate forthe statewide proportion of school buses that fail the safety inspection.How large a sample would you have to take in order to construct a 95% confidence interval estimatefor the true proportion of buses that fail the inspection and achieve a margin of error of plus orminus 2%? (your answer should be an integer)
