An analyst recently collected data on a process consisting of three work elements. Below are the recorded times and the workers performance ratings for five cycles of the job. The data show at least one complete "pattern" of observations for each of the work elements. Determine the standard time using an allowance of 15 percent of the job time. Fill in the blanks for the average observed times, frequencies, normal times, the normal time for the cycle, and the standard time. Round the standard time to two decimal places (no other values should be rounded). Report two decimal places for each response (e.g., 9.25).
