This demonstration may be used to determine confidence intervals for standard deviation and variance. Degrees of freedom go from 1 to 100 and the s-value (sample standard deviation) goes from 0.1 to 50,000. User may enter in values for df, alpha, and s. Output should include a graphic of chi-square curve, lower and upper bounds for confidence intervals.
