- 4. A soda drink bottling company is interested in winning a contract with a popular drink brand. To win the contract the company must show that it is capable of meeting 6o quality. The contract is for the production of 355mL cans, for which a tolerance of +0.5mL is specified. The company believes the facility is in statistical control and has calculated a global value of R 0.15mL and 355.025mL for its production system. The com- pany ran a capability test by obtaining 10 samples (each of 8 elements) on which capability calculations will be performed.
