The assumption of random sampling is necessary to ensure that the sample is representative of the population and to minimize bias. Without random sampling, the hypothesis testing results may not be generalizable to the population. Interval-ratio level of measurement, sample size, and stratification are not necessary assumptions for hypothesis testing.
