Respuesta :

The appropriate nonparametric test for the given research is; One sample Wilcoxon signed rank test.

What is the Non Parametric Test?

A non-parametric test is also called a distribution-free test and it unlike the parametric test, it is usually based on fewer assumptions. Thus, there is typically no need for key parameters like median, mean deviation, mean e.t.c.

Now, the types of Non parametric tests are;

  • Wilcoxon Rank Sum Test
  • Mann Whitney U-test
  • Spearman Correlation
  • Kruskal Wallis Test

In this question, we do not know the distribution of X.

where;

X is the time it takes to walk across a presumably scary portion of campus.

However, we know that X is continuous and so we will use the One sample Wilcoxon signed rank test.
