Game performance of water polo players. Refer to the Biology of Sport (Vol. 31, 2014) study of the physiological performance of top-level water polo players, Exercise 9.24 (p. 513). Recall that data for eight Olympic male water polo players were used to model y = mean heart rate as a straight-line function of x = maximal oxygen uptake. Find an estimate of s, the standard deviation of (p. 513). Give a practical interpretation of this value.

Reference: Exercise 9.24

a. Give the equation of the least squares line.

b. Give a practical interpretation (if possible) of the y-intercept of the line.

c. Give a practical interpretation (if possible) of the slope of the line.
