Question: Problem 7-12 (Algo) How many work cycles should be timed to estimate the average cycle time to within 2 percent of the sample mean with

Problem 7-12 (Algo) How many work cycles should be timed to estimate the average cycle time to within 2 percent of the sample mean with a confidence of 900 percent if a pilot study yielded these times (minutes) 5.3,5,8,5 8,51 61 and 467 The standard deviation is 0.554 minutes per cycle (Uso the "mean time" value to 2 decimal places and other values to 3 decimal places for intermediate calculations. Round up your final answer to the next whole number.) A time study was conducted on a job that contains four elements. The observed times and performance ratings for six cycles are shown in the following table, OBSERVATIONS (minutes per cycle) Element Performance Rating 95% 90 2 3 4 2 0.47 1.42 0.77 1.07 8.42 1.42 8.77 1.02 3 0.37 1.37 2.67 1.02 4 0.37 1.37 0.72 1.07 5 0.37 1.37 0.77 1.87 105 0.37 1.42 2.72 1.12 90 Click here for the Excel Data File a. Determine the average cycle time for each element (Round your answers to 3 decimal places.) Elomont Averago cyclo b. Find the normal time for each element. (Round your answers to 3 decimal places.) Normal timo Element 1 2 3 4 c. Assuming on allowance factor of 12 percent of job time, compute the standard time for this job. (Round your answers to 3 decimal places.) Standard timo Elorant 1 2
