Malaki Curry · Answer 1

Given: X - number of theft crimes

Y - number of burglary crimes

The given regression equation is

ŷ = 1.37x + 110,383.27.

We have to find x for given value of y = 112,450

Using value of y in regression equation gives

112450 = 1.37x + 110383.27

112450 - 110383.27 = 1.37x

2066.73 = 1.37x

x = 1508.562

So the number of theft crimes is 1508.56
