... Conclusion (p-Value) We can quantify the probability (p-Value) of obtaining a test statistic Z0 at least as large as our sample Z0. P( |Z0| > Z ) = 2[1- Φ (|Z0|)] p-Value = P( |2.20| > Z ) = 2[1- Φ (2.20)] p-Value = 2(1 – 0.9861) = 0.0278 = 2.8% Compare p-Value to Level of Significance If p-Value < ...
