Control chart UCL and LCL

Postby suresi00 Thu Dec 07, 2017 1:17 pm

A quality control manager decides to increase his daily sample size from three to six. The size of
the control band will:
A. not determinable from given data
B. None of the other alternatives apply
.
C. decrease
D. remain unchanged
E. increase

Is this variation due to the normal distribution , calculating the sigma?
