Work Sampling You have the following data from a work sampling study. There were three operators sampled and the sampling was done over five, eight$-$hour workdays $($total of $40$ hours$/$operator$).$ In this five$-$day period there were $900$ products produced by these operators. Work using a drill press is one important task performed by these workers. The supervisor says that all of these operators are experienced and excellent employees and should receive a

$110\%$

performance rating and the PFD allowance for this department is

$11\%$

$.$ Each operator was sampled $95$ times and the number of times that the drill press operation was observed was as follows: Operator $1-40$ times; Operator $2-48$ times; Operator

$352$

times. What is the standard time for the drill press operation for this product?
