- To use FRatioCI, you first need to load the Hypothesis Testing Package using Needs["HypothesisTesting`"].
- FRatioCI[ratio,n,m] gives a confidence interval {min,max} for a ratio of variances estimated by ratio.
- For confidence level

and 
where 
is the 
quantile of an F-ratio distribution with n numerator and m denominator degrees of freedom. - FRatioCI is the confidence interval for a ratio of population variances based on sample variances estimated from samples of size
and 
. - The following option can be given:
