You can put this solution on YOUR website! What z value corresponds to 37% of the data between the mean and the z value?
-----
Draw the picture.
Mark off the 37% to the right of the mean
Mark off the 37% to the left of the mean
----
Find the z-value with 50+37 percent of the data to its left::
invNorm(0.87) = 1.1264
----
Find the z-value with 37 percent of the data to its left::
invNorm(0.37) = -0.3319
------------
