Use Technology to Find a Multiple Regression Equation
-A gym teacher uses three exercises to increase arm strength: push-ups, pull-ups, and rope climbing. He has 10 students in small class. The exercises consist of doing as many push-ups as possible in 2 minutes. After a rest the student does as many push-ups as possible in 2 minutes. After a rest the student climbs a rope and the time is recorded in seconds. The data for this class is given below. What is the regression equation?

• A) Rope climb = \(117 - 1.91\) Push-up - \(1.06\) Pull-ups
• B) Rope climb \(= - 1.91 - 1.06\) Push-up \(+ 117\) Pull-ups
• C) Rope climb \(= - 1.06 + 117\) Push-up - \(1.91\) Pull-ups
• D) Rope climb \(= 117 - 1.06\) Push-up \(- 1.91\) Pull-ups
