I'm confused on determining an z score,
For the graph of a standard normal distribution the cumulative area to the left of a z score is 0.4, what is the cumulative area of the right of that Z score?
z = 0.4, would the right area of the score be an -0.4? How should I start, by placing and 0 between 0.4 or puting an -0.4 in right? What should I do next?
