IN SITUATIONS WHERE SAMPLING IS DONE IT IS GENERALLY ASSUMED                    
THAT LARGER SAMPLES PROVIDE MORE INFORMATION ABOUT THE TRUE                     
SITUATION THAN DO SMALLER SAMPLES. THE ADDITIONAL INFORMATION                   
WHICH THE LARGER SAMPLE SIZE BRINGS COULD BE COMPUTED IF                        
WE COULD SOMEHOW MEASURE THE UNCERTAINTY IN THE INFORMATION                     
BOTH BEFORE AND AFTER TAKING THE SAMPLE. SUCH A MEASURE                         
OF UNCERTAINTY EXISTS AND IS SOMETIMES CALLED SHANNON                           
INFORMATION. THIS PROGRAM GIVES BOUNDS ON THE UNCERTAINTY                       
WHEN THE SAMPLING IS COMING FROM A NORMAL DISTRIBUTION WITH                     
BOUNDED VARIANCE.
