Homework: M2 = Assignment 2: Variables SPC and Process Capabil Sample 1 2 Question 4, Problem 30 Part 1 of 3 Aspen Plastics produces plastic bottles to customer order. The quality inspector randomly selects four bottles from the bottle machine and measures the outside diameter of the bottle neck, a critical quality dimension that determines whether the bottle cap will fit properly. The dimensions (in.) from the last six samples are 3 4 5 6 1 3 4 0.571 0.596 0.621 0.589 0.583 0.592 0.621 0.593 0.619 0.618 0.593 0.574 0.596 0.570 0.584 0.604 0.615 0.612 Click the icon to view the table of factors for calculating three-sigma limits for the x-chart and R-chart.
