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?

Push-ups
​		Pull-ups
​		Rope
Climb		​Push-ups
​		Pull-ups
​		Rope
Climb
161369​171968
182056​232249
242546​212152
221859​201663
191565​161774

◦ Rope climb = -1.06 + 117 Push-up - 1.91 Pull-ups
◦ Rope climb = 117 - 1.06 Push-up - 1.91 Pull-ups
◦ Rope climb = -1.91 - 1.06 Push-up + 117 Pull-ups
◦ Rope climb = 117 - 1.91 Push-up - 1.06 Pull-ups
