Is it True or False about the Null Hypothesis?

Question

Is it True that the Null hypothesis does always contain an equality sign?

Answer 1

For the purposes of basic statistics, the null hypothesis is typically that the two groups being compared are equivalent (aka NOT significantly different), thus you would write that with an equal sign. So generally, yes, it's true. However, like all things in life, you could make an very complex exception with a differently designed statistical test.
