Example 11.3. Hypotheses with One Sample of One Measurement Variable
Example 11.4. Hypotheses with Two Samples of One Categorical Variable
Bayesian hypothesis testing helps to answer the question: Can the results from a test or survey be repeated?
Why do we care if a test can be repeated? Let’s say twenty people in the same village came down with leukemia. A group of researchers find that cell-phone towers are to blame. However, a second study found that cell-phone towers had nothing to do with the cancer cluster in the village. In fact, they found that the cancers were completely random. If that sounds impossible, it actually can happen! Clusters of cancer can happen . There could be many reasons why the first study was faulty. One of the main reasons could be that they just didn’t take into account that sometimes things happen randomly and we just don’t know why.

What is a Good Hypothesis? - University of Richmond
Null hypothesis- SCL approach will have no effect on how primary school students learn English skills compared to when they’re taught using a teacher-centered approach
Q. How do I write a good hypothesis statement? - …
Lead the reader to your statement of purpose/hypothesis by focusing your literature review from the more general context (the big picture e.g., hormonal modulation of behaviors) to the more specific topic of interest to you (e.g., role/effects of reproductive hormones, especially estrogen, in modulating specific sexual behaviors of mice.)

The null for a test might be “the mean is equal to 0” and the alternate might be “the mean is not equal to zero”. I can’t see how you would be able to formulate a null/alternate from the test values. Were you given any other information in the question?
