2. Below is a graph of total body weight (in pounds) versus percent of body fat for a random sample of eight U.S. adults. Weight vs. Body Fat For Eight U.S. Adults. Weight in lbs. Percent Body Fat a) (3 pts.) Circle the one outlier on the scatterplot above. Put an X through one influential observation on the scatterplot above. b) (2 pts.) What is the response variable in this situation? c) (6 pts.) The correlation between total body weight (in pounds) versus percent of body fat a person has was calculated to be 0.5876. The value of $r^2$ is ______. Interpret what $r^2$ means in relation to the story problem situation. d) (5 pts.) The equation of the best fit line was calculated as $\hat{y} = 71.25 + 6.4674x$. Use this equation to give the vertical intercept point. Then interpret the vertical intercept point with regards to the story problem situation. Remember to include units of measure in your answer.
