Question
**Probability Distribution Exercise**

A sociologist randomly selects single adults for different groups of three, and the random variable \( x \) is the number in the group who say that the most fun way to flirt is in person. Determine whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied.

| \( x \) | \( P(x) \) |
|--------|----------|
| 0      | 0.093    |
| 1      | 0.337    |
| 2      | 0.412    |
| 3      | 0.158    |

**Questions:**

1. Does the table show a probability distribution? Select all that apply:
   - [ ] A. Yes, the table shows a probability distribution.
   - [ ] B. No, the sum of all the probabilities is not equal to 1.
   - [ ] C. No, the random variable x's number values are not associated with probabilities.
   - [ ] D. No, the random variable x is categorical instead of numerical.
   - [ ] E. No, not every probability is between 0 and 1 inclusive.

2. Find the mean of the random variable \( x \). Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
   - [ ] A. \(\mu = \) ___ adult(s) (Round to one decimal place as needed.)
   - [ ] B. The table does not show a probability distribution.

3. Find the standard deviation of the random variable \( x \). Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
   - [ ] A. \(\sigma = \) ___ adult(s) (Round to one decimal place as needed.)
   - [ ] B. The table does not show a probability distribution.

**Instructions:**
- Evaluate whether the probability values \( P(x) \) add up to 1.
- Confirm that each \( P(x) \) is between 0 and 1.
- Determine the numerical nature of random variable \( x \).
- Calculate mean \(\mu\) and standard deviation \(\sigma\) if the table represents a valid probability distribution.
