b. Use software to access the student survey data, and carry out a chi-square test for a relationship between smoking and living on campus or not. Report the chi-square statistic and the P-value.
c. State whether or not there is statistical evidence of a relationship.
d. Is the sample proportion living off campus higher for the smokers?
