4. Aspen Plastics produces plastic bottles to customer order. The quality inspector randomly selects four bot- tles 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 inches) from the last six samples are Sample 1 2 3 4 5 6 1 0.594 0.587 0.571 0.610 0.580 0.585 BOTTLE 2 0.622 0.611 0.580 0.615 0.624 0.593 3 0.598 0.597 0.595 0.585 0.618 0.607 4 0.590 0.613 0.602 0.578 0.614 0.569 Assume that only these six samples are sufficient, and use the data to determine control limits for an R- and an X-chart
