Male and female students perform equally well in a numerical aptitude test. This statement indicates a:
null hypothesis
Hypotheses are classified by the kind of claim they make, so the wording of the statement identifies its type.
The statement asserts that male and female students perform equally well, that is, that there is no difference between the two groups. A statement of no difference or no relationship is a null hypothesis. It is written in this negative form deliberately, because statistical tests are designed to test a hypothesis of no difference and either reject it or fail to reject it; the researcher hopes to reject the null and thereby support the alternative.
A research hypothesis is the positive claim the investigator actually expects, typically asserting that some difference or relationship does exist. A directional hypothesis goes further and specifies the direction of that difference - saying, for instance, that male students perform better than female students. The statement here does neither, since it claims equality rather than any difference or direction.
Statistical hypothesis is the broader category to which both null and alternative hypotheses belong, being any hypothesis stated in a form that permits statistical testing. It is therefore too general to be the precise answer; the specific type named by a claim of equality is the null hypothesis.
Hence the statement indicates a null hypothesis.
