A small study was conducted on a new procedure for treating atrial fibrillation. The study involved a new way to perform ablation surgery. One method currently being used had a success rate of only 50% in preventing additional episodes of atrial fibrillation within one year. The new method of performing ablation surgery was performed on 8 patients and 6 of the 8 patients did not suffer additional episodes of atrial fibrillation within one year. Choose the statement that best summarizes the significance of this result.
A)Many people would say that this result has both clinical and statistical significance because the probability of success increases from 50% to 75% and the result could have significant impact on
Lives.
B)Although this result may have clinical significance, it does not have statistical significance because the sample size is so small.
C)Although this result may have statistical significance, it does not have clinical significance because the sample size is so small.
D)Although this result may have statistical significance, it does not have clinical significance because the sample was not randomly selected.
