The question displayed in the image asks:

**Pregunta 20: ¿Cuál de las siguientes afirmaciones es correcta en relación al test de Kolmogorov-Smirnov?**
(Which of the following statements is correct regarding the Kolmogorov-Smirnov test?)

Options:
- O Evalúa la multicolinealidad.  
(It evaluates multicollinearity.)
- O Mide la correlación entre más de dos variables explicativas.  
(It measures the correlation between more than two explanatory variables.)
- O Permite averiguar cuando el coeficiente de determinación disminuye.  
(It helps determine when the coefficient of determination decreases.)
- O Evalúa la normalidad de los residuos aleatorios.  
(It evaluates the normality of random residuals.)

The **correct answer** here is:

**"Evalúa la normalidad de los residuos aleatorios"**  
(It evaluates the normality of random residuals.)

The **Kolmogorov-Smirnov test** is used to assess whether a sample follows a specified distribution, most commonly used to test the normality of data.
