Question

Explain how to use the standard normal table to find the probability associated with the shaded area under the curve.

Answer 1

The standard normal table is used to read the area under the bell curve. Most z-tables are to read the area to the LEFT of Z=z as shown in the diagram below. Total area under the curve is one because total probability is always one.  

Answer 2

Answer:

The standard normal table gives areas under the curve to the left of z-scores.

Find the probability in the standard normal table that a value is to the left of 1.9.

Find the probability in the standard normal table that a value is to the left of 0.4.

Subtract the probability of a value being to the left of 0.4 from the probability of a value being to the left of 1.9.
