ACME company is considering on bidding 3,000, 3400, or 3,800 (or not bidding at all) on a job. The charity will choose the lowest bid. ACME estimates that it will cost $235 to prepare a bid and labour and material costs of $2,500 if they win the contract. Based on past contracts of this type, ACME believes it can speculate on thr values of the possible low bids from the competition, if there's any competition, and the associated probabilities are shown: competitors bid amount (if any) Less than $3000. Probability (0.45) Greater than or equal to $3,000 but less than 3,400 Probability (0.33) Greater than or equal to 3,400 but less than 3,800 Probability (0.18) Greater than or equal to 3,800 .

This device is specified as 201.0 + 10.0. In the production of this device, subgroups of six units are taken at periodic intervals and tested. Xbar and R are calculated for each subgroup and used to plot control charts. The results of inspection of 25 subgroups, ΣX = 5,000.00 and ΣR = 277.00. Can the process meet specifications if it is re-centered at 350 ?
