Question

what does a hypothesis determine? what will be tested the number of tests how true a theory is

Explanation:

A hypothesis is a proposed explanation or prediction that guides a research study. Its main role is to define what aspect of a phenomenon or relationship will be investigated (tested). The number of tests is determined by factors like sample size, experimental design, not the hypothesis. A hypothesis is tested to evaluate a theory, but it doesn't directly determine "how true a theory is"—that's the result of testing the hypothesis. So the correct option is the one about what will be tested.

Answer:

A. what will be tested
