Question 1161584: Consider the standard normal distribution curve.
A. What is the area under the curve to the left of z = 1.85?
B. What is probability that a randomly selected member of the population would have a z-score between -0.61 and 2.05?
C. 70.19% of the population have z-scores above what score?

z=1.85 has a value of 0.9678 so that the area under the curve to the left of that is 0.9678 of the total area.
I got the value from the table
between -0.61 and +2.05 use 2nd VARS 2 (normal pdf) (-0.61,2.05) to get 0.7089
use 3invnorm (.7019,0,1) and get z=0.5298 or 0.53
It is worth going back to the table and confirming that.
