Hypothesis testing involves attempting to reject the null hypothesis, not the alternative hypothesis. A hypothesis can be rejected based on statistical evidence, but due to the nature of statistical testing, a hypothesis can never be accepted with 100% certainty; it can only fail to be rejected. Marketing research studies do not attempt to prove results in the absolute sense but rather gather evidence to support or refute a hypothesis. The null hypothesis is assumed to be true until evidence suggests otherwise, not assumed to be false.
