Determine the time for M$20$B$20$ in MTM$1($Use the relevant tables in your book or slides$).$

Calculate the equivalent in TMUs of $0\mathrm{.}0075$ hours per piece, of $0\mathrm{.}248$ minutes per piece, of $0\mathrm{.}0622$ hours per hundred, of $0\mathrm{.}421$ seconds per piece, of $10$ pieces per minute.

What are advantages of work sampling over stopwatch time study?

The Dorben Company is using the work sampling technique to establish standards in its typing pool section. This pool has varied responsibilities, including typing from tape recordings, filing, Kardex posting, and copying. The pool has six typists who work a $40-$hour week. Seventeen hundred random observations were made over a four$-$week period. During the period, the typists produced $9\mathrm{.}001$ pages of routine typing. Of the random observations, $1,225$ showed that typing was taking place. Assuming a $20$ percent allowance and an adjusted performance rating factor of $0\mathrm{.}85,$ calculate the hourly standard per page of typing.
