Pine Valley Bank has three branches. You have been asked to evaluate the efficiency of each. The following inputs and outputs are to be used for the study:

■ input 1 = labor hours used (hundreds per month)

■ input 2 = space used (in hundreds of square feet)

■ input 3 = supplies used per month (in dollars)

■ output 1 = loan applications per month

■ output 2 = deposits processed per month (in thousands)

■ output 3 = checks processed per month (in thousands)

The relevant information is given in the file P04_41.xlsx. Use these data to determine whether any bank branches are inefficient.
