A. We first assume that the null hypothesis is true. And then, we collect the sample from the population and compute the sample test statistic to infer whether our assumption is valid at a given significance level.
B. We do not assume anything. We just collect the sample from the population and compute the test-statistic to infer about the hypotheses at a given significance level.
C. We first assume that the null hypothesis is false. And then, we collect the sample from the population and compute the sample test statistic to infer whether our assumption is valid at a given significance level.
