Relationship between fitness and smoking


Given the data table below, determine if there is a relationship between fitness level and smoking habits:

Low fitness level Medium-low fitness level Medium-high fitness level High fitness level
Never smoked 113 113 110 159
Former smokers 119 135 172 190
1 to 9 cigarettes daily 77 91 86 65
>=10 cigarettes daily 181 152 124 73

You don't have to fully solve for the number here (that would be pretty time-intensive for an interview setting), but lay out the steps you would take to solve such a problem.
