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?
