**Transcription for Educational Use:**

A box contains 5 pennies, 3 dimes, 1 quarter, and 1 half-dollar. A coin is drawn at random. Let x be the value of a coin.

a) Construct a probability distribution for the data.

|      |  $       |  $       |  $       |  $       |
|------|----------|----------|----------|----------|
| X    |          |          |          |          |
| P(x) |          |          |          |          |
| (Write as a decimal) |   |   |   |   |

b) Calculate \( E(X) \) (same as \( \mu \)), \( \sigma^2 \), and \( \sigma \).

Round to two decimal places.

- **Population Mean:** Select an answer = 
- **Population Standard Deviation:** Select an answer = 
- **Population Variance:** Select an answer = 

c) What does the population mean tell us about this problem?
- Select an answer

d) What does the population standard deviation tell us about this problem?
- Select an answer

**Explanation of Components:**

- **Probability Distribution Table:**
  - The table outlines positions to fill with the values \( X \) and their probabilities \( P(x) \) expressed in decimals for each denomination (e.g., penny, dime, quarter, half-dollar). 

- **Calculations for Statistical Measures:**
  - Instructions are provided to calculate the expected value \( E(X) \), which is the population mean \( \mu \).
  - You are instructed to calculate the variance \( \sigma^2 \) and standard deviation \( \sigma \).

- **Questions Exploring Interpretation:**
  - Questions ask you to reflect on what the population mean and standard deviation reveal about the problem, indicating their implications on understanding the distribution of coin values in the box.
