TABLE 12-5 Four Surgical Procedures Currently Are Used to Install Pacemakers. If

question 77

True/False

TABLE 12-5
Four surgical procedures currently are used to install pacemakers. If the patient does not need to return for follow-up surgery, the operation is called a "clear" operation. A heart center wants to compare the proportion of clear operations for the 4 procedures and collects the following numbers of patients from their own records:

They will use this information to test for a difference among the proportion of clear operations using a chi-square test with a level of significance of 0.05.
-Referring to Table 12-5, the decision made suggests that the 4 procedures do not all have the same proportion of clear operations.
