# Permutation test: wild type versus heterozygote

Test the hypothesis that the heterozygote and wild type bout lengths are identically distributed using a permutation test.

Instructions

**100 XP**

- Compute the difference of means (heterozygote minus wild type bout lengths) of the actual data sets, storing the result in the variable
`diff_means_exp`

. The`numpy`

arrays`bout_lengths_wt`

and`bout_lengths_het`

are already in your namespace. - Draw 10,000 permutation replicates of the difference of means using
`dcst.draw_perm_reps()`

. You can use the`dcst.diff_of_means()`

function as well, storing your result in`perm_reps`

. - Compute the p-value, defining "at least as extreme as" to be that the difference of means under the null hypothesis is
**greater**than or equal to that which was observed experimentally. - Print the p-value to the screen.
