A statistical test.
A [test] statistic.
Texting a hypothesis is no different to texting a message! So a piece of word processing software, or even a SMS on a phone will suffice.
A graph is a representation of a thing/system, and can be used to test a hypothesis. For example, if you have a graph of a trend you can find the function of that trend. Then, you can plug in values the graph defines--say, at 2 the graph reaches 5--and if the function works, you know you have modeled the phenomenon correctly. This function testing can work to test a hypothesis, especially in finding trends.
