Question

A. Areas under the Normal Curve: Find the area of the following. Then, illustrate using the

normal curve.

1. 𝑧 = 0.34

2. 𝑧 = 2.12

3. 𝑧 = −1.35

4. 𝑧 = −0.27

5. 𝑧 = 1.07

6. At least 𝑧 = −0.47

7. Between 𝑧 = 0.76 𝑎𝑛𝑑 𝑧=2.34

8. Greater than 𝑧 = 0.78

9. Less than 𝑧 = −0.67

10. Between 𝑧 =−1.52 𝑎𝑛𝑑 𝑧=0.97

Answer 1

1. 0.6331

2.0.9830

3. 0.0885

4.0.3936

5.0.8577

6.1-0.3192=0.6808

7.0.9904-0.7764=0.214

8.1-0.7823=0.2177

9.0.2514

10.0.8340-0.0643=0.7697
