TABLE 13-12
The manager of the purchasing department of a large banking organization would like to develop a model to predict the amount of time (measured in hours) it takes to process invoices. Data are collected from a sample of 30 days, and the number of invoices processed and completion time in hours is recorded. Below is the regression output:
Note: 4.3946E-15 is 4.3946×10 -15

-Referring to Table 13-12, the p-value of the measured F-test statistic to test whether the number of invoices processed affects the amount of time is
A) (4.3946E-15)/2.
B) 4.3946E-15 .
C) (0.0030)/2.
D) 0.0030.
