STAT210prob2.45: Develop Equation 2.50

Description

This data is for developing the following equation...

\frac{{S_1}^2}{{S_2}^2} {F_{1-\alpha/2,{n_2}-1,{n_1}-1}} \frac{<}{ } \frac{{\sigma_1}^2}{{\sigma_2}^2} \frac{<}{ } \frac{{S_1}^2}{{S_2}^2} {F_{\alpha/2,{n_2}-1,{n_1}-1}}

...for a 100(1 - \alpha) percent confidence interval for the ratio {\sigma_1}^2/{\sigma_2}^2, where {\sigma_1}^2 and {\sigma_2}^2 are the variances of two normal distributions.

Usage
