I was using proc freq to calculate sample size for a binomial proportion and I got numbers that disagree with what I have used in the past for 95% confidence with 95% reliability. Using a sample size of 59 I get:
result Frequency Percent Cumulative
Frequency Cumulative
Percent
Fail 0 0.00 0 0.00
Pass 59 100.00 59 100.00
Binomial Proportion for result = Pass
Proportion (P) 1.0000
ASE 0.0000
95% Lower Conf Limit 1.0000
95% Upper Conf Limit 1.0000
Exact Conf Limits
95% Lower Conf Limit 0.9394
95% Upper Conf Limit 1.0000
I was just curious why SAS gives me a confidence just under 94% and not 95%
