The dataset ICU-Admissions contains information on a sample of 200 patients being admitted to the Intensive Care Unit (ICU) at a hospital. One of the variables is HeartRate and another is Status which indicates whether the patient lived (Status = 0) or died (Status = 1). Use the computer output to give the details of a test to determine whether mean heart rate is different between patients who lived and died. (You should not do any computations. State the hypotheses based on the output, read the p-value off the output, and state the conclusion in context.)

Difference = mu (0) - mu (1)
Estimate for difference: -2.12
95% CI for difference: (-11.53, 7.28)
T-Test of difference = 0 (vs not =): T-Value = -0.45
P-Value = 0.653 DF = 60
