Greenhouse Gas Emissions The table below shows annual greenhouse gas emissions. in tons of carbon dioxide ( CO 2 ) , by vehicle fuel efficiency rating in miles per gallon (mpg).

Chapter 13, Problem 16RE, Greenhouse Gas Emissions The table below shows annual greenhouse gas emissions. in tons of carbon

Is there a linear relation, at the | x | > 0.9 level, between vehicle fuel efficiency and greenhouse gas emissions?

To determine

Is there a linear relation, at the |r|>0.9 level, between vehicle fuel efficiency and greenhouse gas emissions?

Explanation of Solution

Given information:

The table below shows annual greenhouse gas emissions in tons of carbon dioxide (CO2), by vehicle fuel efficiency rating in miles per gallon (mpg).

Calculation:

To find the linear correlation coefficient of the given data we feed x values as MPG rating and y values as Tons of CO2 in calculator.

So the correlation of coefficient of the given data is r=0
