question 42

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%
______________________________________________________________

What is the value of this number?

• A)91.3
• B)90.0
