Explanation / Answer

The area under the 2 parts of the curve around mean are 0.4726 each, as shown.

We need to find the z-score corresponding to these values.

We assume a standard normal distribution with mean 0, as shown and standard deviation =1

Area under to the curve under the left tail (unshaded) part = 0.5 -0.4726 = 0.0274

From a standard normal table, this corresponds to a z-score of -1.92

The total area on the left half of the curve and the shaded portion on the right equal 0.5+ 0.4726 =0.9726

From a standard normal table, this corresponds to a z-score of 1.92

So the two z-scores are -1.92, +1.92
