Having hard time with these 2 questions. Wondering if you can answer so that I can match your answer to mine to see if I did the questions correct.

Q1.)Using this information, what is a 95% confidence interval for the proportion of the population (from which this sample of 1687 people was drawn) who would get worse on at least one of the measures related to heart disease?

Q2.) The last two sentences of the article state Medication did not matter. Nothing predicted who would have an adverse response. It sounds like the authors of the original study compared the outcome (adverse response: yes or no) among participants who did or did not take medication.

i.What summary statistic could you use to summarize the association between medication use and adverse response?

ii. What statistical test would be appropriate for testing for this association?

iii. What would be the null and alternative hypotheses?
