TABLE 12-12
The manager of the purchasing department of a large savings and loan organization would like to develop a model to predict the amount of time (measured in hours) it takes to record a loan application. Data are collected from a sample of 30 days, and the number of applications recorded and completion time in hours is recorded. Below is the regression output:

Note: 4.3946E-15 is 4.3946 x 10-15.

-Referring to Table 12-12, the value of the measured t test statistic to test whether the amount of time depends linearly on the number of loan applications recorded is ________.
A) 0.8924
B) 3.2559
C) 15.2388
D) 232.2200

Quizplus · Accepted Answer

The t test statistic measures the strength of the linear relationship between two variables. A value of 15.2388 indicates a strong linear relationship, which is typically much larger than values like 0.8924 or 3.2559, suggesting a significant linear dependency.
