Linear Regression Learning Target Least Squares Regression: A group of asthma patients has an average age of 42 years with a standard deviation of 16.05 years. They experience asthma attacks with a mean duration of 23.8 minutes with a standard deviation of 5.85 minutes. a) Using the raw data below and the summary data in the problem statement, find the least squares regression line to predict duration of an asthma attack from the age of the patient. Age Duration of Attack 35353 30 15 25 28 65 30 50 22 24 b) If a patient is 30 years old, how long would you expect their asthma attack to last? c) That patient's asthma attack actually lasted 15 minutes. What is the residual for this patient? Did the model under or over predict the duration?
