### Educational Content: Understanding Normal Curves

**Task:**
Draw a normal curve with a mean (\( \mu \)) of 70 and a standard deviation (\( \sigma \)) of 19. Label the mean and the inflection points on the graph.

**Instructions:**
Choose the correct graph of the normal curve from the options displayed below.

#### Graph Options:

- **Option A:**
  - This graph displays a normal distribution curve with the mean indicated at 70, and the inflection points marked at 51 and 89.
  
- **Option B:**
  - This graph shows a normal distribution curve with the mean at 89, and the inflection points at 70 and 108.

- **Option C:**
  - This graph illustrates a normal distribution curve where the mean is 51, and the inflection points are 32 and 70.

**Key Concept:**
The inflection points of a normal curve are located one standard deviation (\( \sigma \)) away from the mean (\( \mu \)). In a perfectly drawn normal distribution, these points mark the transition from concave up to concave down on either side of the mean.

**Note:**
Visual analysis of these graphs will help determine the correct option where the mean and inflection points match the provided parameters (\( \mu = 70 \), \( \sigma = 19 \)).
