Glioblastoma multiforme is a particularly deadly form of brain cancer: Approximately 10% of patients who have it survive more than 5 years.

A hospital is testing a new medication to treat glioblastoma multiforme, and they want to know whether the new medication improves the 5-year survival rate. In a sample of 2,436 patients with glioblastoma multiforme who take the new medication, 271 survive more than 5 years.

Use a 1-Prop Z-Test to find a p-value.
