Transcribed Image Text:Swor et al looked at the effectiveness of cardiopulmonary resuscitation (CPR) training in
people over 55 years old. They compared the skill retention rates of subjects in this age
group who completed a course in traditional CPR instruction with those who received chest-
compression only cardiopulmonary resuscitation (CC-CPR). Independent groups were tested
three months after training. The table below shows the skill retention numbers in regard to
overall competence as assessed by video ratings done by two video evaluators. Ref:
Resuscitation 2003:58:177-185.
If we define the following events as:
A = a subject enrolled in the CPR course
B = a subject enrolled in the CC-CPR course
C = a subject was evaluated as competent
D = a subject was evaluated as not competent

Expert Solution
Step 1
Given above is the assessment data of people trained for CPR and CC-CPR. The number of competent and non competent persons is given.
A = a subject enrolled in the CPR course
B = a subject enrolled in the CC-CPR course
C = a subject was evaluated as competent
D = a subject was evaluated as not competent
