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. ŷ = 309,552.15 + 1.31x ŷ = 1.31 + 309,552.15x ŷ = 546,641.84 + 0.64x ŷ = 0.64 + 546,641.84x unable to determine the equation

Step-by-step explanation:

The equation for the least-squares regression is,

where b is the slope and a is the intercept.

They can be found out by,

where,

r = correlation coefficient = 0.84

= standard deviation of y = 44,910

= standard deviation of x = 28,803

= mean of y = 774,140

= mean of x = 354,718

Putting the values,

Therefore the equation is,
