Question

For Luther's data on average velocity and number of pitches, what is the equation of the line of best fit and the absolute value of the correlation coefficient?

a) y = x + 0.5
b) y = x - 0.5
c) y = x + 0.7
d) y = x - 0.7

Answer 1

The equation of the line of best fit is y = x - 0.5, and the correlation coefficient is not provided in the given information.

Step-by-step explanation:

The equation of the best-fit line is y = x - 0.5. To find the equation of the line of best fit, we calculate the slope and y-intercept using the least-squares method. The slope represents the rate of change, and the y-intercept gives the starting point. Since the slope is 1 and the y-intercept is -0.5, the equation of the line is y = x - 0.5.
