Usage
Calculates the 95% confidence interval for inputs k successes on n total number of draws. Returns a percentage value without % sign with one decimal (if more or less digits are desired, use the digits argument).
{{ConfidenceInterval|k|n}}
- 50 success on 100 draws represents a success rate of (50+/-9.8)%
- 250 success on 500 draws represents a success rate of (50+/-4.4)%
- 50 success on 500 draws represents a success rate of (10+/-2.62962)% (displaying up to 5 digits with the digits argument here).
- 100 success on 100 draws represents a success rate of (100+/-3)%
- 0 success on 100 draws represents a success rate of (0+/-3)%
- 4765 success on 4765 draws represents a success rate of (100+/-0.1)%
- 0 success on 365 draws represents a success rate of (0+/-0.8)%
- 100 success on 10 draws represents a success rate of (1000)% (this is a case where the confidence interval makes no sense, thus it is not reported if k > n).
