Notation for one-sided hypothesis testing
I see the following notation for one-sided hypothesis testing: * $H_0$: $K = 2$ * $H_1$: $K > 2$ I would find it more natural to write: * $H_0$: $K \le 2$ * $H_1$: $K > 2$ Assume a situation where $K$ is not, by definition, limited to equal or be higher than two. $K$ is just a dummy variable and 2 a dummy number. Where does the first notation come from and why is it in use?
