Question
Does the length of a surgery patient's stay in the hospital depend on the length of time the
operation took? The table below gives the operative time (in hours) and the length of the hospital
stay (in days) for 13 patients. (Comma separated lists of the data are also provided below the table
to ease in copying the data to R.)

2. Graph the scatter plot of the data together with the best fit line using R. (This portion of the
problem is not graded.)
3. If a patient's operation took 1 hour, how many days should we expect them to stay at the
hospital?
