About 90% of patients suffering from serious heart attack die
within 5 years. In an attempt to reduce the death rate from heart
attack, Green Hospital is creating a new form of treatment.
Recently, they conducted a study with 150 patients, and, among
them, 128 died within 5 years. Type I error is 5%. Use the p-value
approach to say whether there are sufficient evidences to conclude
that death rate due to serious heart attack has been reduced [Setup
