Question:
In Exercise 43, we summarized the relationship between x = height of a student (in inches) and y = number of steps required to walk the length of a school hallway, with the regression line ŷ = 113.6 − 0.921x . For this model, technology gives s = 3.50 and r2 = 0.399.
a. Interpret the value of s.
b. Interpret the value of r2.
