1. Fifty countries are randomly sampled throughout the world and the following two variables are recorded for each country:

x = # cell phones owned per household in that country

y = the average Body Mass Index (BMI, with a higher BMI representing more overweight) among residents of that country

The correlation coefficient for the 50 data points and the result is r = -0.372, p = 0.237.Which of the following interpretations may be concluded?

1. the variables are significantly correlated and having more cell phones causes a smaller BMI.
2. the variables are significantly correlated but having more cell phones does not necessarily cause a smaller BMI.
3. the variables are not significantly correlated and countries with more cell phones have a smaller BMI.
4. the variables are not significantly correlated and countries with more cell phones have a higher BMI.
