Question
### T-Test for Population Mean

In this exercise, a t-test is performed to test a claim about a population mean (\(\mu\)) at a given level of significance (\(\alpha\)), using specific sample statistics provided. The population is assumed to be normally distributed.

#### Given Data:
- **Claim:** \(\mu = 52,600\)
- **Level of Significance:** \(\alpha = 0.10\)
- **Sample Statistics:** 
  - Sample Mean (\(\bar{x}\)) = 52,489
  - Sample Standard Deviation (\(s\)) = 1400
  - Sample Size (\(n\)) = 19

#### Hypotheses:
Select the correct null and alternative hypotheses from the options below:

- **Option A:**
  - \(H_0: \mu \leq 52,600\)
  - \(H_a: \mu > 52,600\)

- **Option B:**
  - \(H_0: \mu = 52,600\)
  - \(H_a: \mu \neq 52,600\)  ✔️ (Correct Answer)

- **Option C:**
  - \(H_0: \mu \geq 52,600\)
  - \(H_a: \mu < 52,600\)

- **Option D:**
  - \(H_0: \mu \neq 52,600\)
  - \(H_a: \mu = 52,600\)

#### Calculating the Standardized Test Statistic:
To find the value of the standardized test statistic, enter the calculation result in the provided field. Make sure to round your answer to two decimal places.

\[ \text{The standardized test statistic is } \boxed{\phantom{0}} \]

The interface includes a t-distribution table icon to assist with finding critical values for hypothesis testing.
