Transcribed Image Text:**Title:** Hypothesis Testing and Confidence Intervals
**Overview:**
In this example, two different simple random samples are drawn from two different populations. The aim is to compare the results from a hypothesis test of \( p_1 = p_2 \) with a 0.05 significance level and a 95% confidence interval estimate of \( p_1 - p_2 \).
- **First Sample:**
- Consists of 30 people with 15 having a common attribute.
- **Second Sample:**
- Consists of 1900 people with 1349 having the same common attribute.
**Steps to Complete:**
1. **Identify the Test Statistic:**
Fill in the blank for the test statistic value rounded to two decimal places as needed.
2. **Identify the Critical Value(s):**
Determine the critical values by rounding to three decimal places as needed. Use a comma to separate answers if necessary.
3. **Conclusion Based on the Hypothesis Test:**
- **Decision Rule:**
- Compare the test statistic to the critical region.
- Decide whether to retain or reject the null hypothesis.
- Determine if there is enough evidence to conclude that \( p_1 \neq p_2 \).
4. **95% Confidence Interval:**
- Compute the confidence interval, rounded to three decimal places, to estimate \( (p_1 - p_2) \).
5. **Conclusion Based on the Confidence Interval:**
- **Interpretation:**
- If 0 is (or is not) in the interval, indicate the implication for the null hypothesis.
6. **Comparing Hypothesis Test Results and Confidence Interval:**
- Compare the outcomes from the hypothesis test and the confidence interval.
- Analyze if the results are consistent, and cross-check the implications for \( p_1 \) and \( p_2 \).
**Graphical Analysis (if applicable):**
- There are check boxes for different hypothesis test options:
- \( H_0: p_1 = p_2 \)
- \( H_0: p_1 \geq p_2 \)
- \( H_0: p_1 \leq p_2 \)
- The alternative hypotheses \( H_1 \) have similar completion checkboxes as above.

![**Title:** Hypothesis Testing with Two Populations
**Description:**
Two different simple random samples are drawn from two different populations. The first sample consists of 30 people with 15 having a common attribute. The second sample consists of 1900 people with 1349 of them having the same common attribute. Compare the results from a hypothesis test of \( p_1 \ne p_2 \) (with a 0.05 significance level) and a 95% confidence interval estimate of \( p_1 - p_2 \).
**What are the null and alternative hypotheses for the hypothesis test?**
- **Option A:**
\( H_0: p_1 \ge p_2 \)
\( H_1: p_1 < p_2 \)
- **Option B:**
\( H_0: p_1 \le p_2 \)
\( H_1: p_1 \ne p_2 \)
- **Option C:**
\( H_0: p_1 = p_2 \)
\( H_1: p_1 \ne p_2 \)
- **Option D:**
\( H_0: p_1 > p_2 \)
\( H_1: p_1 \le p_2 \)
- **Option E:**
\( H_0: p_1 \ne p_2 \)
\( H_1: p_1 = p_2 \)
- **Option F:**
\( H_0: p_1 = p_2 \)
\( H_1: p_1 > p_2 \)
