### Evaluating Methods to Help Smokers Quit SmokingA 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*#### Hypothesesa. **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 Analysisb. **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 Makingd. **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).]#### Explanation of Graphs or Diagrams-

4. Chantix (varenicline) tablets are used as an aid to help people stop smoking. In a clinical trial, 129 subjects were treated with Chantix twice a day for 12 weeks, and 16 subjects experienced abdominal pain (based on data from Pfizer, Inc.)If someone claims that more than 8% of Chantix users experience abdominal pain, that claim is supported with a hypothesis test conducted with a 0.05 significance level. Using 0.18 as an alternative value of P, the power of the test is 0.96. Interpret this value of the power of the test.

A researcher wants to know if mood is affected by music. She conducts a test on a sample of 4 randomly selected adults and measures mood rating before and after being exposed to classic rock music. Test the hypothesis that mood rating decreased after being exposed to classic rock music. The mood ratings for the four participants are provided. Assume that all conditions for testing have been met. Report the null and alternative hypothesis and p-value. At the 1% significance level, state the decision regarding the null hypothesis and the conclusion about the original claim. Round all values to the nearest thousandth. Click the icon to view the mood ratings. OA. Ho Hdifference =0, Ha Hdifference >0; p=0.373; Reject the null hypothesis; there is strong evidence to suggest that exposure to classic rock music decreased mood rating. B. Ho Hdifference =0, Ha Hdifference >0; p=0.373; Fail to reject the null hypothesis; there is not strong evidence to suggest that exposure to classic rock music…
