=The following questions will help you explore fuel efficiency of automobiles. Write your answers on this page.= = = =__Scatterplot Questions__= Create two different scatterplots that compare two categories that you think may impact the fuel efficiency of a car.
 * 1) For scatterplot 1, answer the following questions
 * Identify the two categories you chose and why you thought there might be a relationship between the two BEFORE creating the scatterplot.
 * After creating the scatterplot, do you believe there is a relationship between the two categories? Why or why not?
 * If there appears to be a relationship, does it have a positive or negative slope? What does this mean about the relationship between the two categories?
 * 1) For scatterplot 2, answer the following questions
 * Identify the two categories you chose and why you thought there might be a relationship between the two BEFORE creating the scatterplot.
 * After creating the scatterplot, do you believe there is a relationship between the two categories? Why or why not?
 * If there appears to be a relationship, does it have a positive or negative slope? What does this mean about the relationship between the two categories?

=__Regression Questions__= Create the regession line. Include both the equation and the r2 value on the graph.


 * 1) For scatterplot 1, answer the following questions
 * What is your regression equation? Explain what each part of the equation means in relation to the categories.
 * What is your r2 value? Is this a strong correlation? Why or Why not?
 * Based on parts a and b, can you make any conclusions about your two categories? If so, what conclusions can you make? If not, why not?
 * 1) For scatterplot 2, answer the following questions
 * What is your regression equation? Explain what each part of the equation means in relation to the categories.
 * What is your r2 value? Is this a strong correlation? Why or Why not?
 * Based on parts a and b, can you make any conclusions about your two categories? If so, what conclusions can you make? If not, why not?
