Question
For a random variable x, a new random variable y can be created by applying a linear transformation y = a + bx, where a and b are constants. If the random variable x has mean μₓ, and standard deviation σₓ, then the mean, variance, and standard deviation of y are given by the following formulas:

- Mean: μᵧ = a + bμₓ
- Variance: σ²ᵧ = b²σ²ₓ
- Standard Deviation: σᵧ = |b|σₓ

The mean annual salary for employees at a company is $38,000. At the end of the year, each employee receives a $5000 bonus and a 3% raise (based on salary). What is the new mean annual salary (including the bonus and raise) for the employees?

The new mean annual salary is $ ________.

**Analysis of HD Televisions in Households**

Using the data provided, determine whether it would be unusual for a household to have no HD televisions.

**Data Summary:**

- **Number of Televisions (HD) per Household in a Small Town:**
  - 0 televisions: 26 households
  - 1 television: 445 households
  - 2 televisions: 655 households
  - 3 televisions: 1474 households

- **Probability P(x):**
  - 0 televisions: 0.010
  - 1 television: 0.171
  - 2 televisions: 0.252
  - 3 televisions: 0.567

**Question:**
Choose the correct answer regarding the unusual nature of having no HD televisions in a household.

**Options:**
- **A.** It would be unusual because the probability of having no HD televisions is less than 0.05.
- **B.** It would not be unusual because the probability of having no HD televisions is more than 0.05.
- **C.** It would not be unusual because 26 people have no HD televisions in the town.
- **D.** It would be unusual because 26 people have no HD televisions in the town.
