Two sheet-metal presses are used to produce a part for automotive transmissions. Scrap costs for one critical dimension are excessive. To determine whether there is a difference in mean performance for the two presses, a Six Sigma project team ran a small experiment. The Minitab output for the statistical analysis is shown below. Using a significance level of α = 0.05, the team concludes that:

Your company just landed an order to produce ball bearings for the latest Bazinga fidget spinner. A process capability study was conducted on a sample of 100 balls produced on a new grinding machine. The estimated average diameter is 2.016, and the estimated standard deviation is 0.020. The measurements appear to be normally distributed.  The target dimension is 2 mm, with LSL = 1.9 mm and USL = 2.1 mm. Estimate Cpk. Does this process meet Motorola’s Six Sigma quality level? Explain your answer.
