Explain and answer question B please!
Aspirin prevents blood from clotting and so helps prevent strokes. The Second European Stroke Prevention Study asked whether adding another anticlotting drug named dipyridamole would be more effective for patients who had already had a stroke. Here are the data on strokes collected during the two years of the study: Stroke No Stroke Total Aspirin alone 203 1446 1649 Aspirin + dipyridamole 156 1494 1650 Is there a significant difference in the proportion of...

Please answer all parts to the question(a&b). I will thumbs up!
The Diabetes Control and Complications Trial followed diabetes patients diagnosed with retinopathy before joining the study. They were randomly assigned to one of two treatments and monitored for 6 years. The study found that 128 of the 349 patients assigned to the conventional treatment showed a sustained progression of their original retinopathy. In contrast, only 62 of the 368 patients assigned to the intensive treatment had sustained retinopathy progression....

Please answer all parts to the question (a-f). I will thumbs up!
In the summer of 2002, a group of students took an SRS of size 25 from a compiled list of the 220 top grossing films over the last 11 years. For each film in the sample, the number of products that were subtly planted in the picture per hour was recorded, as well as the films rating. From the rating, we can infer who the target audience is...
