Question
![### Evaluating Methods to Help Smokers Quit Smoking
A researcher wanted to determine which method would help smokers quit smoking. He divided a group of 183 smokers into three groups:
- **Group 1**: Given a patch
- **Group 2**: Given oral medication
- **Group 3**: No intervention (Control Group)
The results of the study are shown in the table below. The researcher's claim is tested using a significance level of \( \alpha = 0.05 \).
#### Table: Results of the Study
| | Group 1 | Group 2 | Group 3 |
|:--------------:|:-------:|:-------:|:-------:|
| **Did Not Quit** | 52 | 54 | 51 |
| **Quit** | 13 | 9 | 4 |
*Source: Harris Poll*
#### Hypotheses
a. **Determine the null and alternative hypotheses.**
- **Option 1:**
- \( H_0 \): The methods for helping people quit smoking are the same.
- \( H_a \): The methods for helping people quit smoking follow a different distribution.
- **Option 2:**
- \( H_0 \): The methods for helping people quit smoking are independent.
- \( H_a \): The methods for helping people quit smoking are dependent.
[Select the appropriate hypotheses based on the study's context.]
#### Statistical Analysis
b. **Determine the test statistic. Round your answer to two decimal places.**
\[ \chi^2 = \_ \_ . \_ \_ \]
c. **Determine the p-value. Round your answer to four decimal places.**
\[ \text{p-value} = \_ . \_ \_ \_ \_ \]
#### Decision Making
d. **Make a decision.**
- Fail to reject the null hypothesis.
- Reject the null hypothesis.
[Select the appropriate decision based on the calculated test statistic and p-value.]
e. **Make a conclusion.**
- There is not sufficient evidence to support the claim that the methods for helping people quit smoking are different.
- There is sufficient evidence to support the claim that the methods for helping people quit smoking are different.
[Select the appropriate conclusion based on the decision from part (d).]
