(Continuous Time Study - Mean Elemental Times)

10 40 * *** * From the following continuous stopwatch time study, 1. Compute the mean elemental times. (Assume elemental times in seconds per piece) 2. Average Elemental Times for elements 1 - 10. (Eliminate inconsistent readings, foreign elements if necessary). (Note: * eliminate) 3. Total Time standards and pieces per hour. Element 1 2 2. 3 4 5 6 7 8 9 Num.
