True/False

SCENARIO 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:
Procedure

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 Scenario 12-5,there is sufficient evidence to conclude that the proportions between procedure B and procedure D are different at a 0.05 level of significance.
