# Aufgabe
Welche der Abbildungen zeigt am deutlichsten eine `r form[i]` Verteilung?
```{r show-plot, echo = FALSE, results="hide", fig.height = 4, fig.width = 6, fig.cap = ""}
gf_dens(~x|z, data = data)
```
```{r questionlist, echo = FALSE, results = "asis"}

# Lösung
```{r solutionlist, echo = FALSE, results = "asis"}
exams::answerlist(ifelse(solutions, "Richtig", "Falsch"), markup = "markdown")
