Q2: Q3: Are there differences in length of stay (in hours) by arrival mode? (Note: You will need to convert length of stay to be in terms of number of hours. You will also need to combine the 'other' groups with the 'walking' group' so you have four groups to examine (Walking, Public Ambulance, Private Vehicle, Private Ambulance).

Firstly, describe the relationships between each of the independent and dependent variables, and then identify which of the variables explain the largest amount of variation in heart rate. If researchers are mostly interested in the association between body temperature and heart rate, why is the effect of age being examined (provide details relevant to your data)
