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
