Question: (Normal Distribution) Setup: Define z to be a z-score with an area of to the right. For example: z0.10 means P(Z > z0.10) = 0.10.

(Normal Distribution) Setup: Define z to be a z-score with an area of to the right. For example: z0.10 means P(Z > z0.10) = 0.10. We would also have, for example: P(Z < z0.10) = 0.10 because of the symmetric property of the normal distribution. Questions: (a) Find P(z0.14 < Z < z0.14). (b) Find P(z/2 < Z < z/2), where is any number between 0 and 1. (c) Find the value of z (rounded to 2 decimals) such that P(Z > z) = 0.039. In addition, state the value of for this part. Hint: It may help to draw a picture of what you want to find
