Question at position 6  Enrique manufactures earrings at his factory in Dublin, OH. He is trying to determine if there is a bottleneck in his welding department that may be slowing down his production of diamond nose rings. To determine if there is a delay Enrique has recorded data from 3 separate days and taken 3 random readings of how long each earring takes (in seconds) to be welded (see table). Calculate the X-bar-bar of the welding process in the earring factory. (round your answer to 2 decimal places) [table] Sample/Day | Day 1 | Day 2 | Day 3 1 | 13.24 | 13.89 | 13.76 2 | 12.56 | 11.98 | 12.34 3 | 15.01 | 14.33 | 12.39 [/table] Answer Enrique manufactures earrings at his factory in Dublin, OH.
