Question
**Title: Understanding Hypothesis Testing in Survey Analysis**

**Introduction:**

An annual survey of first-year college students asks 270,000 students about their attitudes on various subjects. According to a recent survey, 52% of first-year students believe that abortion should be legal. We aim to test the claim that over half of all first-year students believe that abortion should be legal using a 0.05 significance level.

---

**Objective:**

Formulate the null and alternative hypotheses. Choose the correct answer from the options below.

**Options:**

- **A.**  
  \( H_0: p = 0.5 \)  
  \( H_a: p \neq 0.5 \)

- **B.**  
  \( H_0: p = 0.5 \)  
  \( H_a: p > 0.5 \)

- **C.**  
  \( H_0: p = 0.5 \)  
  \( H_a: p < 0.5 \)

- **D.**  
  \( H_0: p < 0.5 \)  
  \( H_a: p = 0.5 \)

**Explanation:**

In hypothesis testing, the null hypothesis (\( H_0 \)) is a statement that there is no effect or no difference. It is the hypothesis that the researcher tries to disprove. The alternative hypothesis (\( H_a \)) is what the researcher wants to prove. Here, the goal is to test whether over half (\( p > 0.5 \)) of the population believes that abortion should be legal.

**Tip for Choosing the Correct Hypothesis:**

- **Null Hypothesis (\( H_0 \)):** Suggest no change or effect, typically \( p = 0.5 \).
- **Alternative Hypothesis (\( H_a \)):** Suggests the effect or difference you want to test, e.g., \( p > 0.5 \).

The correct choice aligns with testing whether more than half believe abortion should be legal, which is option **B.**

By exploring hypothesis testing in this context, students can better understand statistical methods and their practical applications.
