Question

#### Graph Description:
- **X-axis (Differences):** Represents the differences (\( D \)) between the sample means, ranging from -3 to 3.
- **Y-axis (Frequency):** Represents the frequency of each difference observed in the 1000 simulated samples.
- **Distribution Shape:** The distribution is approximately normal, centered around 0, indicating that under the null hypothesis, the differences between the sample means are likely to be close to zero.
#### Question:
Which sample provides the strongest evidence against \( H_0 \)?
- \( D = 2.3 \)
- \( D = 1.4 \)
- Both provide equally strong evidence against \( H_0 \)
**Considerations:**
- Larger absolute values of \( D \) indicate stronger evidence against \( H_0 \).
- Compare the given \( D \) values to the distribution to determine which is further from the center (0).
### Answer:
* \( D = 2.3 \) provides the strongest evidence against \( H_0 \).
This inference is based on the fact that \( D = 2.3 \) falls further from the center of the distribution compared to \( D = 1.4 \), suggesting it is less likely to occur under the null hypothesis.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe9f05283-2131-42d7-a756-eb5144058e13%2F58aeb7b2-216f-441c-a36e-66fa5a9e4298%2Feo9m8j_processed.png&w=3840&q=75)

The figure below shows a randomization distribution based on 1000 simulated samples for hypotheses \( H_0: \mu_1 = \mu_2 \) vs \( H_a: \mu_1 \neq \mu_2 \). The statistic used for each sample is \( D = \bar{X}_1 - \bar{X}_2 \). Which sample provides the strongest evidence against \( H_0 \)?
