The following data are for a time study completed by James in a casting process at a Foundry. Three elements A, B and C were observed and times recorded in minutes. The extended 10% basic times not within 1 10% limit of the average observed times, are to be regarded as unreliable. For each element rest allowance is 5% and a rating of 100% is standard.
