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.  Test the significance of the individual predictor variables at

Push-ups ​	Pull-ups ​	Rope Climb	​	Push-ups ​	Pull-ups ​	Rope Climb
16	13	69	​	17	19	68
18	20	56	​	23	22	49
24	25	46	​	21	21	52
22	18	59	​	20	16	63
19	15	65	​	16	17	74

◦ Consider removing the variable "Pull-ups" because it is not a good predictor of "Rope Climb Time".
◦ Consider removing the variable "Push-ups" because it is not a good predictor of "Rope Climb Time".
◦ Both explanatory variables have a significant linear relationship with the response variable.
◦ Consider removing both variables because neither is a good predictor of "Rope Climb Time".
