Question: In Exercise 44, we summarized the relationship between x = temperature in degrees Fahrenheit and y = chirps per minute for the striped ground cricket,

In Exercise 44, we summarized the relationship between x = temperature in degrees Fahrenheit and y = chirps per minute for the striped ground cricket, with the regression line ŷ = –0.31 + 0.212x. For this model, technology gives s = 0.97 and r² = 0.697.

a. Interpret the value of s.

b. Interpret the value of r².

Exercise 44

The scatterplot shows the relationship between x = temperature in degrees Fahrenheit and y = chirps per minute for the striped ground cricket, along with the regression line ŷ = −0.31+0.212x.
