In this week’s episode Greg and Patrick discuss how we might flip the traditional null and alternative hypothesis testing procedures to move us from tests of literal equality to tests of practical equivalence. Along the way they also discuss tough love, horseshoes and hand-grenades, Patrick’s Driving School, Cheyenne Mountain, So Long and Thanks For All the Fish, isn’t that convenient, why people hate us, systolic blood pressure, *real* doctors, I Can’t Drive 55, splash zones, Gallagher, Dilbert, and being precisely equal.
