MA207-B Spring 2008 Regression Modelling Project - Problem 10

Length of stay data at a certain hospital is available for 105 patients who had coronary bypass surgery and were over the age of 55.

Use the data in your comma delimited file to construct a regression model that uses the age of the patient to predict the length of stay.

You should answer the questions on the assignment page that apply to all problems.

For this specific problem, answer the following questions:

How would you interpret the slope of the regression line in this problem?
How would you interpret the intercept of the regression line in this problem?
Were there any outliers or questionable data points? If so, how did you handle them?
Did you use a log transform in this model? If so, explain why you chose to use a transform.
