A team of consultants has identified a set of 10 clinical symptoms they believe may help an insurance company predict how long a person will be off work after suffering whiplash injury in a car accident.Each symptom is assessed separately as 0=absent, 1=present. To determine exactly how useful these 10 symptoms are, 200 patients with whiplash injuries were assessed within 7 days of their accident and then followed up until all had returned to work.Which of the following methods is best for analyzing the results from this study. _Multiple linear regression _Single linear regression _Pearson correlation coefficient of total symptom score against time off work. _Spearman correlation coefficient of total symptom score against time off work
