WILL GIVE A THUMBS UP
Given,
x = age
y = Rentals
The regression line is,
a)
We predict the values by using regreesion equation,
Age(x) | Rental(y) | Predicted values() |
35 | 8 | 9.355 |
43 | 9 | 7,379 |
49 | 7 | 5.897 |
64 | 1 | 2.192 |
42 | 8 | 7.626 |
30 | 10 | 10.59 |
b)Residual
Age(x) | Rental(y) | Predicted values() | Residuals |
35 | 8 | 9.355 | -1.355 |
43 | 9 | 7,379 | 1.621 |
49 | 7 | 5.897 | 1.103 |
64 | 1 | 2.192 | -1.192 |
42 | 8 | 7.626 | 0.374 |
30 | 10 | 10.59 | -0.59 |
c)Residual standard deviation
where, df = n - number of parameters.
Age(x) | Rental(y) | Predicted values() | Residuals | |
35 | 8 | 9.355 | -1.355 | 1.8360 |
43 | 9 | 7,379 | 1.621 | 2.6276 |
