Avandia is a drug used to treat diabetes, but it may cause an increase in heart attacks among a population that is 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 the other treatments.

a. are these proportions from matched-pairs data?

b. what is the result of the appropriate hypothesis test, using the α = .05 level of significance?

c. interpret the results of the test you conducted in question b.

d. construct a 95% confidence interval for the difference in the true proportion of heart attacks for patients on avandia versus other treatments.

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
