An industrial engineering team redesigned a workstation layout to reduce average assembly cycle time for a high‑volume product. Historically, the mean assembly time for this task is μ=12.0minutes per unit. After implementing the new layout, a random sample of 64 units is observed. The sample mean cycle time is x=11.2minutes. From prior studies, the population standard deviation of assembly time is known to be σ=1.6minutes. Management believes the new layout reduces average cycle time, meaning the population mean should be less than 12 minutes.Select the appropriate null hypothesis (H0) and alternative hypothesis (H1).
