1. What percentage of the area of the standard normal distribution is between z=-1.00 and z=+1.00? How do you know this?
----
P(-1 < z < 1) = normalcdf(-1,1) = 0.6827
==============================================
2. Find the z-score for the standard normal distribution where:
Area is about equal to 0.95 to the left of z.
invNorm(0.95) = 1.645
