A proper hypothesis is one that has at least a superficially reasonable quality to it, it has some plausibility as an explanation for whatever it is that you are trying to explain. If it is obviously ridiculous, then it does not qualify as a proper hypothesis. In addition, from a scientific viewpoint a hypothesis should be testable in some way. If there is no way to test your hypothesis then what you are doing is philosophy, not science.
Generally, creating a hypothesis is a no-win situation. The hypothesis you devise must be provable false. Your data will either prove your hypothesis false or it will fail to prove the hypothesis false. You can never prove a proper hypothesis true. Science does not prove truth, it simply discards the false.
Observation, Research, Hypothesis, Experiment, Conclusion, and Communication
The proper order of the steps of the scientific method typically includes: 1) making observations, 2) formulating a hypothesis, 3) conducting experiments to test the hypothesis, 4) analyzing the data, and 5) drawing conclusions. Based on the results, the hypothesis may be accepted, rejected, or revised. Finally, the findings are often shared with the scientific community.
Scientific theories can be disproved. This is a key part of the scientific method, creating hypothesis that can be disproved if they are incorrect. However, you can never really prove a hypothesis - you can find evidence that either fits or doesn't fit. If it doesn't fit the hypothesis needs to be revised or thrown out. If the evidence supports the hypothesis, there may be something that you are missing which may reject the hypothesis.

"A hypothesis is a proposed answer to a question. To answer the question raised by your observations, the hypothesis must be testable." it means that you need to be able to prove that your hypothesis is true or not by creating an experiment and collect/analyze the data
An example of an instruction from the Scientific Method is creating a hypothesis.

There can be no proper answer since it is not known whether the alternative hypothesis is one sides or two sided.
