1. **Problem Statement:**
We are given that the heights of Filipino young women are normally distributed with mean $\mu = 50.5$ inches and standard deviation $\sigma = 2$ inches. We want to find the fraction of women taller than 69 inches.
2. **Given:**
- Mean $\mu = 50.5$
- Standard deviation $\sigma = 2$
- Height threshold $x = 69$
3. **Required:**
Find $P(X > 69)$ where $X$ is the height.
4. **Formula:**
To find the probability for a normal distribution, we convert to the standard normal variable $Z$ using:
$$Z = \frac{X - \mu}{\sigma}$$
Then use the standard normal distribution table or calculator to find $P(Z > z)$.
5. **Solution:**
Calculate $Z$:
$$Z = \frac{69 - 50.5}{2} = \frac{18.5}{2} = 9.25$$
6. **Interpretation:**
A $Z$-score of 9.25 is extremely high, far in the tail of the normal distribution.
7. **Probability:**
Using standard normal tables or a calculator, $P(Z > 9.25)$ is effectively 0 (practically zero).
8. **Conclusion:**
The fraction of Filipino young women taller than 69 inches is nearly zero.
9. **Graph description:**
The normal curve is centered at 50.5 with a spread determined by $\sigma=2$. The area to the right of 69 inches (far right tail) is almost zero, indicating very few women exceed this height.
