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 number of additional minutes required per additional component serviced.
What is the value of this number?
A)32.441
B)11.6205
C)8.121
D)0.7988
E)19.058
