Modeling jumps 2012 Here are the summary statistics for the Olympic long jumps and high jumps displayed in the previous exercise.

a) Write the equation of the line of regression for estimating High Jump from Long Jump.

b) Interpret the slope of the line.

c) In a year when the long jump is 8.9 m, what high jump would you predict?

d) Why can’t you use this line to estimate the long jump for a year when you know the high jump was 2.25 m?

e) Write the equation of the line you need to make that prediction.
