Evaluating the randomness of the sample is not a step in hypothesis testing. However, it is important to ensure that the sample is selected randomly in order to make valid inferences about the population from which it was drawn. The main steps in hypothesis testing are stating the null and alternative hypotheses, choosing the appropriate statistical test, selecting a significance level, collecting data and performing the test, and making a decision based on the results.
