2 (a) The following data refers to the study conducted for an operation. Table shows actual time for the elements in minutes.
i) Element no. 2 is machine element.
ii) Consider observation as abnormal & delete the same if they are more than 20% of average time of the element.
iii) Take performance rating as 110.
iv) Assume personal & fatigue allowance as 29% of the normal time.
Estimate the basic time & standard time for the operation.
