A Study Was Carried Out to Investigate the Relationship Between

Multiple Choice

A study was carried out to investigate the relationship between x = the number of components needing repair and y = the time of the service call (in minutes) for a computer repair company. The number of components and the service times for a random sample of 20 service calls were used to fit a simple linear regression model. Partial computer output is shown below. ______________________________________________________________
The regression equation is Time = 32.441 + 11.6205 Number ​ S=19.058, R-Sq=91.3%, R-Sq(adj) =90.0%
______________________________________________________________
One of the numbers in the above computer output indicates the magnitude of a typical difference between an observed service time and the service call time predicted by the linear model.
What is the value of this number?
​

A) 8.121
B) 0.7988
C) 11.6205
D) 12.31
E) 19.058
