1.
Determine the explanatory and response variables. Write them below:
Explanatory = Response =
2.
Create a scatterplot of the data on the plot to the left. Label your axes carefully.
3.
Describe the plot: list the form, direction, and strength. Also note if there are any outliers.
4.
Use the plot above to help answer the following: If a car has a weight of 3200 lbs, what would you estimate the MPG would be for that car? EXPLAIN HOW YOU ARRIVED AT YOUR ANSWER!!

The following data comes from a sample of statistics students. Create a scatterplot with Arm Span as the Explanatory and Height as the Response Variables.
