Hypothesis test: are the b-values different?

Perform the hypothesis test sketched out on the previous exercise. The variables mags_pre and mags_post are already loaded into your namespace, as is mt = 3.

Slice out the magnitudes of earthquakes before 2010 that have a magnitude above (or equal) the completeness threshold and overwrite mags_pre with the result. Do the same for mags_post.
Compute the observed difference in mean magnitudes, subtracting the magnitudes of pre-2010 earthquakes from those of post-2010 earthquakes.
Generate 10,000 permutation replicates using dcst.draw_perm_reps(). Use dcst.diff_of_means as the argument for func.
Compute and print the p-value taking "at least as extreme as" to mean that the test statistic is smaller than what was observed.
