Question

The dataset US States includes information on the 50 US States, including the percent of the population of each state that eats at least five servings of fruits and vegetables a day and the percent of each state that is obese. The figure below shows a scatterplot of these two variables. It turns out that one state is missing from the scatterplot. For this state, 35% of the population eats at least five servings of fruit and vegetables a day and 35% of the population are obese. If we add this state to our scatterplot and subsequent calculations, we expect the correlation coefficient between FiveVegetables and Obese to Select one: a. decrease b. remain unchanged c. the effect on the correlation coefficient cannot be determined. d. increase

Explanation / Answer

Since the general trend of data is decreasing but the point which we are adding is upward from the general trend,the correlation coefficient is expected to increase.

Option d is correct.
