R Assignment

A director of research at an acute care hospital observes an increase in patients returning to the hospital within 30 days. The director determines that this is harmful to patients as well as financially harmful to the hospital. The dataset hospital1 contains data on a study the director conducted to determine what factors are related to returning to the hospital within 30 days. The director wants to test the hypothesis that patients with and without spouses are not equally likely to return within 30 days. The null hypothesis would be that patients with and without spouses are equally likely to return to the hospital within 30 days.
