In retrospect this is actually rather silly since hypothesis testing can be applied to anything, but for some reason I was super intrigued when I learned about the hypothesis testing of regression coefficients - that's C&R and hypotest rolled into one, and its application to finding the significance of different correlations is pretty darn amazing imo!
