Veličina sigma1
Z následujícího vzorce vyjádři veličinu uvedenou v závorce:
\( \large U=\frac{\bar{x}_1-\bar{x}_2}{\sqrt{\frac{\sigma_1^2}{n_1}+\frac{\sigma_2^2}{n_2}}}\quad\left[\sigma_1\right] \)
\( \sigma_{1}=\sqrt{\frac{\left(\bar{x}_{1}-\bar{x}_{2}\right)^{2}-\frac{\sigma_{2}^{2}}{n_{2}} \cdot U^{2}}{U^{2}} \cdot n_{1}} \)
\( \sigma_{1}=\sqrt{\frac{\left(\bar{x}_{1}-\bar{x}_{2}\right)^{2}-\frac{\sigma_{2}^{2}}{n_{2}} \cdot U}{U^{2}} \cdot n_{1}} \)
\( \sigma_{1}=\sqrt{\frac{\left(\bar{x}_{1}+\bar{x}_{2}\right)^{2}-\frac{\sigma_{2}^{2}}{n_{2}} \cdot U^{2}}{U^{2}} \cdot n_{1}} \)
\( \sigma_{1}=\frac{\left(\bar{x}_{1}-\bar{x}_{2}\right)^{2}+\frac{\sigma_{2}^{2}}{n_{2}} \cdot U^{2}}{U^{2}} \cdot n_{1} \)
