Yes, but ideally a single hypothesis for one set of tests is one sentence long.If, say, you measure the viscosity of different types of ketchups and the texture of different types of ketchup, then there should be two "if... then... because" hypotheses because hypotheses should ideally be a single sentence. :)
A hypothesis can be framed in either a positive or negative manner. The results will show that this WILL occur. The results will show that this WILL NOT occur.
A hypothesis is an educated guess. Basically what meteorologist do. For example: The low temperature for new york city tonight is 37 degrees. Now I cannot guarantee that, but it is my hypothesis.
