Insights into the Concept of Hypothesis Testing (Part 14)

Alpha decreases beta increases

This is continuation to the data on Population 1 and Population 2 given in yesterday’s BLOG. When alpha is 0.025(z = 1.96) beta is 0.1866 and when alpha reduces to 0.005 (z = 2.55) beta increases to 0.3538. This is explained in the diagram. The mathematics behind it will be explained in the next blog which is also the concluding part of the series “Insights into the concept of Hypothesis Testing”.
