Question: How many work cycles should be timed to estimate if the maximum error is 2 seconds of the sample mean with a confidence of 99

  1. How many work cycles should be timed to estimate if the maximum error is 2 seconds of the sample mean with a confidence of 99 percent. A pilot study yielded these times (seconds): 25, 27, 23, 28, 26, 25, 24, 28, and 23. (z=2.58).
  2. A work measurement analyst in the DORBEN Company took 10 observations of a high-production job. He rated each cycle and then computed the mean normal time for each element. The element with the greatest dispersion had a mean of 0.30 minutes and a standard deviation of 0.03 minutes. If it is desirable to have sampled data within 5 percent of the true data, how many observations should this time study analyst take of this operation? (z=2.62).
