You will NOT be able to copy and paste a graph into the Discussion Board, so you should copy your graph to a Word Document and attach it to your post.

Determine the following information on your selected data set. Be sure to answer all questions using complete sentences.

1. What are the two variables? Do you think there might be a correlation between the two variables (before you analyze the data)?
2. Create a scatterplot with a simple linear regression (see video in Live Binder).
3. What is the linear regression (prediction line) equation? What is the coefficient of determination ?
4. Do you think that there is a strong positive or strong negative correlation? Why or why not? Is this result what you expected?
5. Attach the scatterplot to your post.
