Question:
The Metro Food Services Company conducted a time study for 10 cycles of a job assembling ham and cheese sandwiches, which we will consider to be a sample. The average cycle time, T , for the job was 0.361 minutes, computed by dividing the total time for 10 cycles of the job, 3.61, by the number of cycles, 10. The standard deviation of the sample was 0.03 minutes. The company wants to determine the number of cycles for a time study such that it can be 95 percent confident that the average time computed from the time study is within 5 percent of the true average cycle time.
