Question

Find the corresponding area between 𝑧 = 0 and each of the following.

1. z = 0.85

2. z = 1.27

3. z = 2.86

4. z = −1.05

5. z = −2.96

Answer 1

1.

$$P(0<Z<0.85)=0.8023-0.5=0.3023$$

2.

$$P(0<Z<1.27)=0.8980-0.5=0.3980$$

3.

$$P(0<Z<2.86)=0.9979-0.5=0.4979$$

4.

$$P(-1.05<Z<0)=0.5-0.1469=0.3531$$

5.

$$P(-2.96<Z<0)=0.5-0.0015=0.4985$$
