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.)Step 1:Step 2:Step 3: Step 4:Step 5:

Question
Answer:
Answer:Step-by-step explanation:Given that Advandia is a drug used to treat diabetes, but it may cause an increase in heart attacks among a population already susceptible.Sample size n =1`456Sample proportion of persons having heart attack p1= 27/1456 = 0.0186II sample Size = 2895p2 = sample proportion = 41/2895 = 0.0142a) Not matched pair data but independent proportionsb) Step 1:  [tex]H_0: p_1=p_2\\H_a: p_1 > p_2[/tex](right tailed test at 5% significance level)Step 2:  Test statistic z = 1.0995Step 3:  p value = 0.13567Step 4:  Since p >0.05 accept null hypothesis.There is no 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.Step 5:
