### Conducting a Multinomial Chi-Square Goodness of Fit Test

You are conducting a multinomial Chi-Square Goodness of Fit hypothesis test for the claim that the 4 categories occur with the following frequencies:

\[ H_o : p_A = 0.3; \, p_B = 0.4; \, p_C = 0.15; \, p_D = 0.15 \]

### Task

Complete the table. Report all answers accurate to three decimal places.

#### Frequency Table

| Category | Observed Frequency | Expected Frequency |
|----------|--------------------|--------------------|
| A        | 13                 |                    |
| B        | 29                 |                    |
| C        | 18                 |                    |
| D        | 13                 |                    |

### Questions

1. **What is the chi-square test-statistic for this data?**

   \[ \chi^2 = \]

2. **What is the P-Value?**

   \[ \text{P-Value} = \] 

### Instructions

- Calculate the expected frequency for each category using the given proportions.
- Apply the chi-square formula to determine the test-statistic.
- Use the test-statistic to find the P-value corresponding to the chi-square distribution.
