You have been asked to evaluate the efficiency of the Port Charles Police Department. Three precincts are to be evaluated. The inputs and outputs for each precinct are as follows:

■ input 1 = number of policemen

■ input 2 = number of vehicles used

■ output 1 = number of patrol units responding to service requests (thousands per year)

■ output 2 = number of convictions obtained each year (in hundreds)

You are given the data in the file P04_43.xlsx. Use this information to determine which precincts, if any, are inefficient.
