x: Age of criminal: Independent variable
y: Age of victim: Dependent variable
a) The regression equation is y = b*x + a
Here a is intercept and b is a slope.
x | y | xy | x^2 | |
33 | 25 | 825 | 1089 | |
25 | 20 | 500 | 625 | |
29 | 25 | 725 | 841 | |
18 | 22 | 396 | 324 | |
13 | 16 | 208 | 169 | |
Total | 118 | 108 | 2654 | 3048 |
= 2654
= 3048
= 23.6
= 21.6
n = 5
So the regression equation is
= 0.400*X + 12.167
b)
Criminal = X = 22
= 0.400*X + 12.167 = 0.400*22 + 12.167 = 20.960
