Normal Probability Distribution

The normal probability distribution is a fundamental concept in statistics. Let's examine the options given.

1. A. a bell-shaped distribution: This is true, as the graph of a normal distribution resembles a bell curve, where most of the data points cluster around the mean.

2. B. all of the answers: This option suggests that all other options are correct. We need to verify this first.

3. C. a continuous distribution: This is also true. The normal distribution is defined for all real numbers, making it a continuous probability distribution.

4. D. symmetric: This is accurate as well. The normal distribution is symmetric around its mean.

Conclusion

Since options A, C, and D are all correct and align with the properties of the normal probability distribution, the answer is:
