The second slide is the first part of the question and the first slide is the second part of the question.

**Use a 0.05 level of significance and test the hypothesis that there is no difference between the starting annual salaries.**

**State the null and alternative hypotheses:**

- \( H_0 \): The two populations of salaries are identical.
- \( H_1 \): The two populations of salaries are not identical.

1) \( H_0 \): Median salary for public accountants = median salary for financial planners.  
   \( H_1 \): Median salary for public accountants \(\neq\) median salary for financial planners.

2) \( H_0 \): Median salary for public accountants - median salary for financial planners = 0.  
   \( H_1 \): Median salary for public accountants - median salary for financial planners \(\neq\) 0.

3) \( H_0 \): Median salary for public accountants - median salary for financial planners \(\leq\) 0.  
   \( H_1 \): Median salary for public accountants - median salary for financial planners > 0.

4) \( H_0 \): Median salary for public accountants - median salary for financial planners \(\geq\) 0.  
   \( H_1 \): Median salary for public accountants - median salary for financial planners < 0.

**Find the value of the test statistic:**

### Hypothesis Testing for Salary Differences

**Objective:**  
Use a 0.05 level of significance to test the hypothesis that there is no difference between the starting annual salaries of public accountants and financial planners.

#### Step 1: State the Null and Alternative Hypotheses

- **Option 1:**
  - \( H_0 \): The two populations of salaries are identical.
  - \( H_a \): The two populations of salaries are not identical.

- **Option 2:**
  - \( H_0 \): Median salary for public accountants = Median salary for financial planners.
  - \( H_a \): Median salary for public accountants ≠ Median salary for financial planners.

- **Option 3:**
  - \( H_0 \): Median salary for public accountants ≤ Median salary for financial planners.
  - \( H_a \): Median salary for public accountants > Median salary for financial planners.

- **Option 4:**
  - \( H_0 \): Median salary for public accountants ≥ Median salary for financial planners.
  - \( H_a \): Median salary for public accountants < Median salary for financial planners.

#### Step 2: Conduct the Test

**Find the value of the test statistic:**
- \( W = \) [Enter value]

**Find the p-value (Round your answer to four decimal places):**
- p-value = [Enter value]

#### Step 3: Make a Conclusion

**What is your conclusion?**

- Reject \( H_0 \): There is sufficient evidence to conclude that there is a significant difference between the starting annual salaries of public accountants and financial planners.
- Do not reject \( H_0 \): There is not sufficient evidence to conclude that there is a significant difference between the starting annual salaries of public accountants and financial planners.

Use this guide to complete your hypothesis test for comparing salaries. Ensure you enter the values for the test statistic and p-value to proceed with the analytical decision.
