The monthly absolute estimate of global (land and ocean combined) temperature indexes (degrees C ) in 2000 and 2001 are: 2000: 12.28, 12.63, 13.22, 14.21, 15.13, 15.82, 16.05, 16.02, 15.29, 14.29, 13.16, 12.47
2001: 22.44, 12.55, 13.35, 14.22, 15.28, 15.99, 16.23, 16.17, 15.44, 14.52, 13.52, 12.61
a) Graph the data and fit a regression line to predict 2001 temperatures from those in 2000. Is there a significant regression at ∝ = 0.05? What is P-value?
b) Estimate the correlation coefficient.
