For a sample of 16 people, the error would be 4/16 = 25%. This a large error since the range of YES vs NO is from 0-100% if 12 people answered yes and 4 people answered no then your result would be: . Percentage yes = 75 +/- 25% . ... For a sample fo 1000 people, the error would be SQRT(1000)/1000 = 33/1000 = 3%. If 750 answered yes and 250 answered no then your result would be: . ...

. To see where a script produces an error use the command: sh -x script argument . The -x option to the sh command tells it to print commands and their arguments as they are executed. You can then see what stage of the script has been reached when an error occurs. Other debugging options . Example .
