Answer: 1.88

Solutions/Discussion:

To find the z-value that allows us to be 94%, look up (1-.94)/2 = .03 inside the negative z-table. When you do, you\'ll notice that .03 falls closer to .0301 than to .0294, so the z-critical values is -1.88 and +1.88.

Note: The z-table that I am using can be found on page 1 of the following pdf.
