Work Sampling

You have the following data from a work sampling study. There were five operators sampled and the sampling was done

over three, eight$-$hour workdays $($total of $24$ hours$/$operator$).$ In this three$-$day period there were $175$ products produced by

these operators. Work using a vertical bandsaw is one important task performed by these workers. The supervisor says

that each of these operators are experienced and excellent employees and should receive a $110\%$ performance rating and

the PFD allowance for this department is $9\%.$ Each operator was sampled $55$ times and the number of times that the drill

press operation was observed was as follows: Operator $120$ times; Operator $228$ times; Operator $321$ times;

Operator $422$ times; Operator $523$ times. What is the standard time for the drill press operation for this product?

MTM$-1$

An operator walks $8$ paces away from her workstation and she picks up an impact hammer $($weighs $15$ pounds$)$ from a

shelf that is at mid$-$chest level and requires the hand movement of $14$ inches to grasp the hammer. The hammer sits on the

shelf in a position that varies a bit. She pulls the hammer off the shelf and carries it back to her workstation and sets it

down on the work surface in a precise location $($requires moving the hammer about $16$ inches horizontally$).$ She then

stoops to mid$-$shin level and grabs the handle of a bucket $(6\mathrm{.}8$ pounds$)$ which she then lifts and precisely places the bucket

next to the impact hammer.
