Answer 1

The standard normal distribution

1. $P23$

$$P(Z<z)=0.23$$

$$z=-0.7388$$

2. $P51$

$$P(Z<z)=0.0251$$

$$z=-0.7388$$

3. $P63$

$$P(Z<z)=0.63$$

$$z=0.3319$$

4. $P49$

$$P(Z<z)=0.49$$

$$z=-0.0251$$

5. $P88$

$$P(Z<z)=0.88$$

$$z=1.1750$$

6. $P93$

$$P(Z<z)=0.93$$

$$z=1.4758$$

7. $P90$

$$P(Z<z)=0.90$$

$$z=1.2816$$

8. $P12$

$$P(Z<z)=0.12$$

$$z=-1.1750$$

9. $P75$

$$P(Z<z)=0.75$$

$$z=0.6745$$

10. $P100$

$$P(Z<z)=1$$

$$z=undefined$$
