1)Develop a regression equation for predicting current investment based on college debt. What is the expected change in current investment for each additional dollar of college debt? Give your answer to four decimal places.

2)What is the predicted current investment for an individual who had a college debt of $5000? Give your answer to two decimal places.

3)What proportion of the variation in current investment is explained by college debt? Give your answer to four decimal places.
