True

A statistical hypothesis test does test the researcher’s hypothesis.

In most research situations, the goal is to reject the null hypothesis, not to fail to reject it.

A decision to reject the null hypothesis means that the data do provide evidence of a treatment effect: the independent variable did have an effect on the dependent variable.

If the data do not provide convincing evidence that the treatment does have an effect, then the correct statistical decision is to fail to reject the null hypothesis, not to reject it.

For a hypothesis test, the critical region is defined as the set of test statistics that are very unlikely (very low probability) of being obtained if the null hypothesis is true.
