The table below lists chocolate consumption (kg per capita) and the numbers of Nobel Laureates (per 10 million people) for several different countries (from Data Set 16 in Appendix B). Is there a correlation between chocolate consumption and the rate of Nobel Laureates? How could such a correlation be explained?

Use the rank correlation coefficient to test for a correlation between the two variables. Use a significance level of α = 0.05.
