100' NAME--STAT06
110'
120' DESCRIPTION--CALCULATES THE SIGN TEST CONFIDENCE INTERVAL
130' USING FRACTIONAL COUNTS.
140'
150' SOURCE--UNKNOWN
160'
170' INSTRUCTIONS--PUT DATA IN LINE 900 AND FOLLOWING.
180' MAKE SURE DATA LINE NUMBERS DO NOT EXCEED 919. FIRST
190' DATA PUT IN IS N, THE NUMBER OF THE DATA, THEN C, THE CRITICAL
200' VALUE (FROM A TABLE OF CRITICAL VALUES FOR THE SIGN
210' TEST, SEE KURTZ, "BASIC STATISTICS"). THEN ENTER THE DATA
220' ITSELF. BE SURE THERE ARE NO MORE THAN 1000 NUMBERS.
230' SAMPLE DATA ARE IN LINES 900 AND 910.
