Since xxx subgroup xxxxx n = 5, = 0.577, = 0, = 2.114

Control xxxxxx xxx R-chart:

xxx x x 2.98

xxxx x �� EMBED Equation.3 = (2.114)(2.98) x xxxxxx

xxxx = xxxxxx xxxxx Equation.3 x (0)(2.98) = x

xxxxxxx limits for X-bar xxxxxxx

CL x x xxxxxx

UCL = x xxxxxx xxxxx Equation.3 x 71.928 x xxxxxxxxxxxxx = 73.6475

xxxx = – xxxxxx EMBED xxxxxxxxxx x 71.928 – (0.577)(2.98) = xxxxxxx

xxx x chart xxx xxxxx xxxxx xxx shown xxxxxx

Here all the xxxxxx are xxxxxx the control limits. So xxx xxxxxxx xx xx control.
