Question: how to calculate the area between two z scores?
Answer: Step 1: Split your z-scores at the tenths place. 03. Step 2: Look in the z-table for your z-scores (you should have two from Step 1) by finding the intersections. For example, if you are asked to find the area from z= -0.46 to z= -0.40, look up both 0.40 and 0.46 (see note below about negative numbers).
