Is there a linear correlation between chocolate consumption and the rate of Nobel Laureates? Run a hypothesis test to test the claim that there is a linear correlation. If there is a correlation between chocolate consumption and the rate of Nobel Laureates, can we describe it with an equation so that we can predict the rate of Nobel Laureates if given the rate of chocolate consumption? In other words, what is the equation of the regression line? What would you predict is the rate of Nobel Laureates in a country, which consumes 9.1 kg of chocolate per capita?

Question

If you want to win a Nobel Prize, should you study subjects like physics, chemistry, and economics, or should you just eat more chocolate? The table below lists chocolate consumption (kg per capita) and the numbers of Nobel Laureates (per 10 million people) for each of 23 different countries. See Data Set 16 “Nobel Laureates and Chocolate” in Appendix B, where the countries are identified.
