The table gives the winning heights for the Olympic pole vault competitions in the 20th century. (a)
Question:
(a) Make a scatter plot and decide whether a linear model is appropriate.
(b) Find and graph the regression line.
(c) Use the linear model to predict the height of the winning pole vault at the 2000 Olympics and compare with the winning height of 19.36 feet.
(d) Is it reasonable to use the model to predict the winning height at the 2100 Olympics?
