WebIn the above, example, the power of the hypothesis test depends on the value of the mean \(\mu\). As the actual mean \(\mu\) moves further away from the value of the mean \(\mu=100\) under the null hypothesis, the power of the hypothesis test increases. It's that first point that leads us to what is called the power function of the hypothesis ...
