The correlation between incidence of pancreatic cancer and alcohol consumption is 0.78 while the correlation between incidence of pancreatic cancer and amount of exerciseis-0.89. From this we can conclude

a) An increase in the amount that people exercise would cause incidence of pancreatic cancer to decrease.

b) That the correlation between pancreatic cancer incidence and alcohol consumption is stronger than the correlation between incidence of pancreatic cancer and amount of exercise because negative correlation coefficients suggest weak correlation.

c) That, using the same data, the R2 in a regression of incidence of pancreatic cancer on amount of exercise would be 0.7921.

d) all of the above.

e) None of the above.
