ResourceFunction["NormalCI"][μ,σ] gives a confidence interval based on a normal distribution. |
Details and Options
ResourceFunction["NormalCI"][μ,σ] gives a confidence interval {min,max} centered at μ based on a normal distribution with location parameter μ and scale parameter σ.
ResourceFunction["NormalCI"] is the confidence interval for a population mean based on a sample mean μ and standard error σ if the true population variance is known.
The following option can be given:
| ConfidenceLevel | 0.95 | probability associated with a confidence interval |
Examples
Basic Examples (1)
A 95% confidence interval based on the normal distribution:
