Hypothesis testing is an important statistical tool which lets us challenge conventional wisdom. We designate the "null hypothesis" to be to conventional wisdom ("pigs cannot fly") and then examine the probability of observing certain phenomenon ("seeing a flying pig out the window") assuming the null hypothesis is true. If this probability is sufficiently low, we can reject the null ...
This solution outlines the importance of hypothesis testing and explains, using an example, how to create a null and alternative hypothesis.
