Hypothesis testing provides a basis for taking ideas or theories that someone initially develops about the economy or investing or markets, and then deciding whether these ideas are true or false.

We use right tail hypothesis testing to see if the z score is below the significance level critical value, in which case we cannot reject the null hypothesis as true. In statistical hypothesis testing, the critical values of a statistical test are the boundaries of the acceptance there can be one or more than one critical value.

The critical value approach and the p-value approach give the same results when testing hypotheses the p-value approach has the advantage in that you just need to compute one value, the p-value, to do the test.
