Then solve for the x bar for both UCL and LCL

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 Bottle Sample 1 2 3 4 1 2 3 0.607 0.622 0.596 0.614 0.618 0.625 0.622 0.612 0.605 0.613 0.622 0.598 0.621 0.585 0.617 0.597 0.573 0.586 0.609 0.606 0.617 0.613 0.584 0.601 4 5 6 Compute the range R and the sample mean x for each sample.
