Were you able to assign all the tasks to the theoretical minimum number of workstations? e) The total idle time per cycle for the process = seconds (enter your response as a whole number). f) The efficiency of the assembly line with 5 workstations = \% (enter your response as a percentage rounded to one decimal place). If one used 6 workstations instead of 5 , the efficiency of the assembly line would be = \% (enter your response as a percentage rounded to one decimal place)
