Question: In casting metal parts, molten metal flows through a gate into a die that shapes the part. The gate velocity plays a critical role in die casting. A firm that casts cylindrical aluminum piston examined 12 types formed from the same alloy. How does the cylinder wall thickness influence the gate velocity chosen by the skilled workers who do the casting? If there is a clear pattern, it can be used to direct new workers or to automate the process. Analyze these data and report your findings.
