FRQ Practice: The Great Plains Railroad (2005 Q3)

This activity is based on the 2005 AP Statistics Free Response question #3. This question requires students to determine if a linear model is appropriate, interpret computer output for a LSRL, interpret the value of the correlation coefficient and determine if a prediction can be made from the model. A self-assessment screen at the end allows students to describe how they think they did and where they feel they had difficulties.
