| Question | Answer |
| Intervalový odhad \(\mu\), známe \(\sigma^2\) | \[\overline{X_n} \pm Z_{\frac{\alpha}{2}} \frac{\sigma}{\sqrt{n}}\] |
| Intervalový odhad \(\mu\), neznáme \(\sigma^2\) | \[\overline{X_n} \pm t_{\frac{\alpha}{2}, n-1} \frac{s}{\sqrt{n}}\] |
| Intervalový odhad \(\sigma^2\) | \[ \frac{(n-1) s^2}{\chi_{\frac{\alpha}{2}, n-1}} \le \sigma^2 \le \frac{(n-1) s^2}{\chi_{1-\frac{\alpha}{2}, n-1}} \] |
| Testování hypotéz | \(H_0\) - nulová hypotéza, zamítnutí = silný výsledek \(H_A\) - alternativní hypotéza |
