a) Find the equation of the least-squares line. Identify and interpret the slope and the y - intercept.

Slope: -0.27556; if the year is increased value of time is decreased by 0.2756 seconds

Y-intercept: 603.4304; If the year is 0, then the predicted value of time is 603.4304 seconds

b) Find the correlation coefficient and interpret.

Correlation Coefficient: -0.95112
