Pooping dogs In the interest of determining whether animals are affected by the earth’s magnetic field, researchers recorded the direction dogs faced while pooping. Yes, they really researched this! They used a null hypothesis that dogs are equally like to face any direction versus an alternative that they have a preference for north-south alignment (along the magnetic field lines). With a statistical test for points on a circle that is not covered in this course, they found that, under stable magnetic field conditions, the P-value was 6.2 10 . × −8

a) Interpret this P-value in the context of this study.

b) Write a conclusion for this test.
