I can give you some answers to help you do this assignment. I have no idea what your research is on, so creating the null and alternate will be impossible, but I can give you an example.

Hypothesis testing is used to verify your theory. It is done by testing the null or opposite hypothesis. When the null is proven, your theory cannot be correct or needs some adjustment. Hypothesis testing tests for correlations, relevance, ranges, and levels of confidence. The null will point out there is no relationship, nothing in the observable data to show that the theory is true. The alternative hypothesis shows there is a relationship or that there is truth proven in the data.

Null: H0: Men are not smarter than dogs.
Alternative:H1: men are smarter than dogs.

The alternative states the opposite of the null or a difference. There can be a null and alternative that looks like, H0: x = y H1: x< y. There is no ambiguity if the null fails.

One tail and two tailed hypothesis testing: One tail ...
