A kinesiology major wanted to predict VO2max based on the one-mile run. To develop the regression equation, she obtained VO2max values (ml/kg/min) in the exercise physiology laboratory on 18 students. Two days later, she measured the same 18 students on the one-mile run with scores reported as total time in seconds. The data are as follows: X Y r = -.94 Subject One-mile run time (seconds) VO2 max (ml/kg/min) 1 250 60.3 2 315 57.2 3 420 55.4 4 410 51.4 5 436 52.5 6 511 45.6 7 460 38.4 8 510 41.5 9 530 39.6 10 586 33.2 11 591 37.7 12 600 40.1 13 626 32.0 14 643 35.4 15 650 33.7 16 675 35.9 17 710 27.4 18 720 25.3 Calculate means for one-mile run and VO2 = = Calculate the slope of the line (b) using this formula: Interpret your answer: Calculate the y-intercept (a) using this formula: What is the regression equation?

A kinesiology major wanted to predict VO₂max based on the one-mile run. To develop the regression equation, she obtained VO₂max values (ml/kg/min) in the exercise physiology laboratory on 18 students. Two days later, she measured the same 18 students on the one-mile run with scores reported as total time in seconds. The data are as follows:

	X	Y	r = -.94
Subject	One-mile run time (seconds)	VO₂ max (ml/kg/min)
