Can I get help with 19 please ### Hypothesis Testing: Treatment Independence**Objective**: To test the claim that treatment is independent of the reaction (occurrence of headaches).**Significance Level**: 0.05Given Data:| | Drug | Placebo ||-------------|------|---------|| Headaches | 18 | 20 || No Headaches| 82 | 70 |**Steps to be Included**:1. **Formulate the Hypotheses**: - Null Hypothesis (H0): Treatment is independent of the reaction (i.e., the treatment has no effect on the occurrence of headaches). - Alternative Hypothesis (H1): Treatment is not independent of the reaction (i.e., the treatment has an effect on the occurrence of headaches).2. **Determine the Test Statistic**: - Use the Chi-Square test for independence. - Calculate the expected frequencies for each cell in the contingency table.3. **Calculate the Chi-Square Test Statistic**: - Use the formula: χ² = Σ [(Observed - Expected)² / Expected]. - Compare the observed frequencies in the table to the expected frequencies assuming the null hypothesis is true. 4. **Determine the Critical Value and P-value**: - Use a Chi-Square distribution table to find the critical value for α = 0.05 and degrees of freedom (df) = (rows - 1) * (columns - 1). - Calculate the p-value associated with the test statistic.5. **Make a Decision**: - If the test statistic exceeds the critical value or if the p-value is less than 0.05, reject the null hypothesis. - Otherwise, do not reject the null hypothesis.**Visual Representation**:There is a table representing the frequency of individuals experiencing headaches or no headaches after receiving either a drug or placebo:- **Treatment Group (Drug)**: - 18 individuals reported headaches. - 82 individuals reported no headaches.- **Control Group (Placebo)**: - 20 individuals reported headaches. - 70 individuals reported no headaches.The table aids in calculating the expected frequencies and, subsequently, the Chi-Square test statistic.
