Read the following scenario and complete each of the four problem sets below:

A. Use the z-table to determine the following probabilities. Sketch a normal curve for

each problem with the appropriate probability area shaded.

1. P(z > 2.34)

2. P(z < -1.56)

3. P(z = 1.23)

4. P(-1.82 < z < 0.79)

5. Determine the z-score that corresponds with a 67% probability
