How come I am getting a negative area for my answer with Module 4 Spreadsheet Assignment?
ANSWER: Quick solution is you are talking about an area between two z scores problem. This can be asked as between __ and __. Or, from __ to ___. You are not subtracting in the correct order. Switch the order of the z-scores.
YOU ALWAYS SUBTRACT: LARGER Z – SCORE – SMALLER Z SCORE.
YOU SHOULD BE DRAWING THE CURVES FOR ALL PROBLEMS SO THAT MEANS: Z-SCORE TO THE RIGHT – Z-SCORE MOST LEFT
