For a 94% level of confidence, the z-value is approximately 1.88. This is because the confidence level corresponds to the central area under the normal distribution curve, and for 94%, the tails (both sides combined) have 6% of the area, leaving 3% in each tail. The z-value that leaves 3% in the tail is about 1.88.
