**Probability Distribution of Dogs per Household**

The following details a probability distribution for the number of dogs per household in a small town:

| Dogs | Probability |
|------|-------------|
| 0    | 0.622       |
| 1    | 0.236       |
| 2    | 0.094       |
| 3    | 0.026       |
| 4    | 0.014       |
| 5    | 0.008       |

**Tasks:**

(a) *Calculate the Mean, Variance, and Standard Deviation of the Probability Distribution.*

- **Mean (μ):** Compute the expected value by multiplying each number of dogs by its probability and summing the results. 
  \(\mu = \sum (x \cdot P(x))\)
  
  \(\mu = \boxed{\ } \) (Round to one decimal place as needed.)

- **Variance (\(\sigma^2\)):** Compute the variance by finding the expected value of the squared deviations from the mean.
  \(\sigma^2 = \sum ((x - \mu)^2 \cdot P(x))\)
  
  \(\sigma^2 = \boxed{\ } \) (Round to one decimal place as needed.)

- **Standard Deviation (\(\sigma\)):** The standard deviation is the square root of the variance.
  
  \(\sigma = \boxed{\ } \) (Round to one decimal place as needed.)
