Lessons

Notes:
Instead of using the Standard Normal Distribution to find the Z-score relating to the significance level, all you need to do is put the Test-Statistic on the Standard Normal Distribution and see if the “smaller” area (called the P-Value) is less than the given significance level (α\alpha).

\cdot P-Value \leq α\alpha \Rightarrow H0H_0 is false
\cdot P-Value > α\alpha \Rightarrow Fail to reject H0H_0
