Correct Question:
Tim is investigating the relationship between the number of years since a tree was planted and the height of the tree in feet. His data are shown in the table. Years Since Tree was Planted vs. Height of Tree
Years since the tree was planted, x
Height of tree in feet, y
2, 17, 3, 25, 5, 42, 6, 47, 7, 54, 9, 69
Using a regression calculator, what is a good prediction for the height of the tree when it is 100 years old?
