An advertising company collected data on the number of new contracts signed, y, and the number of presentations, x, made in each of six months. The summary statistics are
n = 6 $\bar{x}$ = 34 $\bar{y}$ = 7.1 S_xx = 1750 S_xy = 36.45 S_yy = .78
Determine the proportion of variation in y that is explained by linear regression. Round your answer to three decimal places.
