Calculate confidence intervals for ratio of two population variances and ratio of standard deviations. Assume that samples are simple random samples and taken from normal populations.
a) $\alpha =0.05,\text{}{n}_{1}=30,\text{}{s}_{1}=16.37,\text{}{n}_{2}=39,\text{}{s}_{2}=9.88$
b) $\alpha =0.01,\text{}{n}_{1}=25,\text{}{s}_{1}=5.2,\text{}{n}_{2}=20,\text{}{s}_{2}=6.8$

For the 1s orbital of the Hydrogen atom, the radial wave function is given as: $R(r)=\frac{1}{\sqrt{\pi}}(\frac{1}{{a}_{O}}{)}^{\frac{3}{2}}{e}^{\frac{-r}{{a}_{O}}}$ (Where ${a}_{O}=0.529$ ∘A)
