Aspirin prevents blood from clotting and helps prevent strokes. The Second European Stroke Prevention Study asked whether adding another anticlotting drug named dipyridamole would make a difference for patients who had already had a stroke. Here are the data on strokes during the two years of the study: Aspirin alone Apsirin & Dipyridamole Ho: P. Ha: P₁ Number of Patients This test is two-tailed. 200 What is the test statistic? 200 Is there a significant difference in the proportion of strokes in the two groups? Test at a = 0.10. Round your answers to three decimal places, and round any interim calculations to four decimal places. Fill in the hypotheses below where p₁ denotes the proportion of patients in the aspirin group who suffered a stroke and på denotes the proportion of patients in the aspirin & dipyridamole group who suffered a stroke. Number of Strokes P₂ 60 P₂ 54 Part 2 of

Question
### Effectiveness of Anticlotting Drugs in Stroke Prevention Aspirin is known for its ability to prevent blood clotting, which in turn helps prevent strokes. The Second European Stroke Prevention Study investigated the potential benefits of adding another anticlotting drug, dipyridamole, for patients who had already experienced a stroke. Below are the study's findings over a two-year period: | | Number of Patients | Number of Strokes | |-------------------------------------------|--------------------|-------------------| | Aspirin alone | 200 | 60 | | Aspirin & Dipyridamole | 200 | 54 | The study aimed to determine whether there is a significant difference in the proportion of strokes between the two groups. The test was conducted at a significance level (α) of 0.10. Results and interim calculations should be rounded to four decimal places, with final answers rounded to three decimal places. #### Hypothesis Statements - Null Hypothesis (\( H_0 \)): \( p_1 = p_2 \) - \( p_1 \): Proportion of patients in the aspirin group who suffered a stroke. - \( p_2 \): Proportion of patients in the aspirin & dipyridamole group who suffered a stroke. - Alternative Hypothesis (\( H_a \)): \( p_1 \neq p_2 \) This is a two-tailed test. ### Question - What is the test statistic?
