Answer:

Step-by-step explanation:

Given that Erin took a treadmill test to check her own potential of having a heart attack. Her family had a 70% risk of heart attack.

Erin took a treadmill test to check her own potential of having a heart attack. The doctors told her that the reliability of the stress test is 67%.

When the test predicted that Erin will not have a heart attack, it reliability is 0.67

But she had a heart attack

i.e. Prob for test saying no heart attack but she had heart attack

=P(test is wrong)*P(she had heart attack)

=(1-0.67)(0.70)

=0.33*0.70

=0.231
