Diabetes:

advandia is a drug used to treat diabetes, but it may cause an increase in heart attacks among a population already susceptible. a large study found that out of 1,456 diabetics who were treated with avandia, 27 of them had a heart attack during the study period. this was compared with 41 heart attacks among a group of 2,895 participants who were given other treatments for their diabetes. the researchers want to determine if there is evidence to suggest that there is a significant increase in the proportion of people who suffer heart attacks when using avandia compared to other treatments.

a)are these proportions from matched-pairs data?

b)what is the result of the appropriate hypothesis test, using ? = 0.05 level of significance? (note: list out each step in your hypothesis testing procedure and show all of your work.)
