The mean and standard deviation for number of robberies in the U.S. from 2000 to 2015 are x̄ = 354,718 and sx = 28,803. The mean and standard deviation for number of assaults in the U.S. for the same time period are ȳ = 774,140 and sy = 44,910. The correlation coefficient is r = 0.84. Find the equation for the least-squares regression line for number of assaults compared with number of robberies.

B. ŷ = 1.31 + 309,552.15x
C. ŷ = 546,641.84 + 0.64x
D. ŷ = 0.64 + 546,641.84x
