1. Given a standardized normal distribution (with a mean of zero and a standard deviation of 1), determine the following probabilities by drawing a normal curve and identifying the area under the curve. Draw a normal distribution curve and identify the area of interest.
2. P (Z > 1.96) =?
3. P (Z > - 1.37) =?
4. P (- 1.96 < Z < -0.25) =?
5. What is the value of Z if only 15% of all possible Z values are larger?

Please show work/steps. Thank you!
