Question

Which of the following is a plausible value for the correlation coefficient between income and deaths? a- +0.7 b- – 0.06 c- +0.2 d- – 1.0 The following scatterplot displays the 2009 per capita income versus number of deaths due to traffic accidents per 100,000 people for each of the 50 states plus the District of Columbia. Which of the following is a plausible value for the correlation coefficient between income and deaths? a- +0.7 b- – 0.06 c- +0.2 d- – 1.0

Explanation / Answer

Just by looking at the scatterplot we can conclude that the correlation will have a negative sign since the slope of best fit line have to have a negative slope

Now the other thing that have to be noted that the correlation for this scatterplot is not very strong because of the outliers and the plots are not that linear in nature

So our final answer is

Option (b) -0.06
