( 120+ 125+ 126+ 124+ 120)÷5
=6 15÷5
= 123 (piece)
Average daily throughput in Li Shifu:
( 125+ 123+ 128+ 1 17+ 127)÷5
=620÷5
= 124 (piece)
A: Master Zhang handles 123 pieces on average every day, and handles 124 pieces on average every day.
(2) Because 124 > 123,
So Li Shifu processes more parts every day.
124- 123= 1 (pieces)
A: Li Shifu processes more parts every day, more than 1.
