If the sum of the task times required to produce a product is 45 minutes and the cycle time for the same product is 10 minutes, the theoretical minimum number of workstations is 5 using the assembly-line balancing procedure.

true

Which of the following basic types of production layout formats is one which similar equipment or functions are grouped together?

You have just determined the actual number of workstations that will be used on an assembly line to be 8 using the assembly-line balancing procedure. The cycle time of the line is 10 minutes and the sum of all the tasks required on the line is 60 minutes. Which of the following is the correct value for the resulting line's efficiency?

.75

You have just determined the actual number of workstations that will be used on an assembly line to be 6 using the assembly-line balancing procedure. The cycle time of the line is 5 minutes and the sum of all that tasks required on the line is 25 minutes. Which of the following is the correct value for the resulting line's efficiency?

.8333

Using the assembly-line balancing procedure, which of the following is the theoretical minimum number of workstations if the task times for the six tasks that make up the job are 4, 6, 7, 2, 6, and 5 minutes, and the cycle time is 10 minutes?
