1) The manager of a warehouse would like to know how many errors are made when a productâ€™s serial number is read by a barcode reader. There are 24 errors after 1000 scans. Is it reasonable for the manager to expect less than 5% errors in 1000 scans?
2) Just to be sure, the manager has more samples taken. There are 36 errors after 1000 scans. Is t reasonable for the manager to expect less than 5% errors in 1000 scans?
