SOLUTION: find area under normal curve above z = 1.28 EQUIVALENT: 1.28 = 0.3962 how do i get the area "ABOVE" of its z score?

Question 1168457: find area under normal curve
above z = 1.28
EQUIVALENT:
1.28 = 0.3962
how do i get the area "ABOVE" of its z score?

Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
The z-score of 1.28 corresponds to probability 0.8997. That is probability of everything to the left or all z-scores LESS than 1.28.
The area above that z-score is the complement or 1-0.8997 or 0.1003 or 10.03%.
Can do on calculator VARS2Normalcdf(1.28, 6)ENTER. Note, you can use any number higher than 6--it represents SD, Don't ever need to use normal pdf .
1.28 is a useful z-value, as is 1.645, 1.96,2.328, and 2.576.
