Q2 (a) A time study analyst timed an assembly operation for 30 cycles, and then computed the average time per cycle, which was 18.75 minutes. The analyst assigned a performance rating of 0.96 and decided that an appropriate allowance was 15 percent. Assume the allowance factor is based on the workday.

A preliminary study yielded a mean of 5.2 minutes and a standard deviation of 1.1 minutes. Determine the total number of observation needed for these two cases: (a) A maximum error of + or - 6 % (b) A maximum error of 40 minutes
