Precision Machinery has set standard times for its field representatives to perform certain jobs. The standard time allowed for routine maintenance is 20 hours (i.e., "standard output" =0.05 jobs per hour). One of Precision's field representatives records the results below. Calculate the rep's efficiency for each customer and her average efficiency. The rep's average efficiency is %. (Enter your response rounded to one decimal place.) The rep's average efficiency is \%. (Enter your response rounded to one decimal place.) According to this measure of her performance, she the efficiency standard for performing routine maintenance
