Therefore, z = – 0.2231 as the complement probability was looked up in the table. 4) Note: Find the closest probability values to 0.6 in the standard normal distribution Table and do the interpolation which results in z= 0.2533. Note: Find the closest z values to 0.477 in the standard normal distribution Table and do the interpolation which results in P(Z ≤ 0.477) = 0.6833
