What is the mean of the distribution?
Correct

What is the standard deviation of the distribution?

To answer these questions properly, let’s first clarify what kind of distribution \( X \) represents, as the initial prompt is incomplete.

### What kind of distribution is \( X \)?

Based on the options provided:

- **Standard Normal Distribution**: This is a specific type of normal distribution where the mean \( \mu = 0 \) and the standard deviation \( \sigma = 1 \).
- **Chi-Square Distribution**: This is a distribution for a variable that is the sum of squared standard normal variables.
- **Binomial Distribution**: A discrete distribution representing the number of successes in a fixed number of independent Bernoulli trials.
- **Normal Distribution**: A general distribution characterized by a bell-shaped curve, defined by a mean \( \mu \) and standard deviation \( \sigma \).

### If \( X \) follows a **Standard Normal Distribution**:

- The mean of the distribution is \( 0 \).
- The standard deviation is \( 1 \).

### If \( X \) follows a **Normal Distribution**:

- The mean \( \mu \) is not fixed; it would depend on the specific normal distribution you are dealing with.
- The standard deviation \( \sigma \) is also not fixed and depends on the specific normal distribution.

#### Conclusion:

- If \( X \) is a **Standard Normal Distribution**: 
  - **Mean**: \( 0 \)
  - **Standard Deviation**: \( 1 \)

If \( X \) is not explicitly stated to be standard normal but just **normal**:
  - **Mean**: \( \mu \) (depends on the specific distribution)
  - **Standard Deviation**: \( \sigma \) (also depends on the specific distribution)

Please clarify if you need more detailed explanations, or if the variable \( X \) follows a general normal distribution. Would you like to explore further?
