Determining Random times and Finding Idle Time Percentage Using the random number table given on page 703 of the text book, determine the random times to make visits. Obtain 12 good observation times for each 4 hours before noon and 4 hours after noon for 5 days. Write the times in the table below and plot them on the weekly production sheet. Since it takes 5 minutes to complete one visit, ensure that the random are at least 5 minutes apart. Calculate % idle time using the weckly production sheet. Count the number of times your nards iniersect the black purtion of the ban and pot tlus number in the hov at the end of the fine. Then and the sumher of idle vivervations and divile thas total by do. Tus gwes you the pertentage of the weeh that the operator was idle by the randown shipling provalure. Now conipare your answer with the actual idle pertentage of-15.2 percent, which was originally obtainod by time winly Flgure 242 Demonstration of the work sampling method. Working time and idle time for one operator for live consecutive working ditys.
