Then the null and alternative hypotheses will be:
Then<em> test statistic</em> will be calculated using survey data and its p-value is evaluated under certain <em>significance level. </em>If the p-value is less than the significance level, the null hypothesis can be rejected in favor of alternative hypothesis.
