Fisher's method in SciPy

Suppose you read five different papers on the role of a healthy diet on cancer diagnoses, with reported p-values loaded in the list p_values = [0.04, 0.13, 0.001, 0.09, 0.01]. In each case the papers are all assessing the null hypothesis that healthy diet has no relationship on cancer diagnosis, while the alternative is that there is a relationship.

Use these p-values in Fisher's method using SciPy.

The package stats from SciPy have been loaded for you.
