### Hypothesis Testing with a t-Test

To test the claim about the population mean \( \mu \) at a given level of significance \( \alpha \) using the provided sample statistics, we start by considering the following:

- **Claim**: \( \mu = 51,200 \)
- **Significance Level**: \( \alpha = 0.01 \)
- **Sample Statistics**: 
  - Sample mean (\( \bar{x} \)): 50,985
  - Standard deviation (\( s \)): 2300
  - Sample size (\( n \)): 20

Assume the population is normally distributed.

#### Instructions

1. **Use a t-test** to evaluate the claim.
2. **Determine the null (\( H_0 \)) and alternative (\( H_a \)) hypotheses** from the options provided.

#### Options for Hypotheses

- **A**. \( H_0: \mu \leq 51,200 \)  
  \( H_a: \mu > 51,200 \)

- **B**. \( H_0: \mu = 51,200 \)  
  \( H_a: \mu \neq 51,200 \)

- **C**. \( H_0: \mu \neq 51,200 \)  
  \( H_a: \mu = 51,200 \)

- **D**. \( H_0: \mu \geq 51,200 \)  
  \( H_a: \mu < 51,200 \)

#### Additional Information

- Click the icon to view the t-distribution table.

Select the correct null and alternative hypotheses based on the context of the test and the claim stated.
