SCENARIO 13-12
The manager of the purchasing department of a large saving 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:

-Referring to Scenario 13-12,the degrees of freedom for the t test on whether the number of loan applications recorded affects the amount of time are
A)1
B)28
C)29
D)30

The degrees of freedom for a t-test are typically calculated as the sample size minus one. Given that there is no specific sample size mentioned in the question, if we assume a sample size of 29 (a common assumption for such questions), the degrees of freedom would be 29 - 1 = 28.
