How many work cycles should be timed to estimate the average cycle time to within 1 percent of the sample mean with a confidence of 95.0 percent of a pilot study yielded these times (minutes): 4.2, 47, 5.2, 5.0, 6.0, and 4.5? The standard deviation is 0.631 minutes per cycle. (Use the "mean time" value to 2 decimal places and other values to 3 decimal places for Intermediate calculations.
