With z =3, the control limits for the mean chart are :

UCLx- ____________ ounces (round to three decimal places)

LCLx- ______________ ounces (round to three decimal places)

c) the control limits for the R-chart are:

UCLr= _______________________________ ounces (round tot hree decimal places)

LCLR= ____________________ ounces (round to three decimal places)

Based on the x chart is one or more samples beyond the conrol limits yes/ no

based on the r chart is one or more samples beyond the control limits? yes/ no

A process that is considered to be in control measures an ingredient in ounces. Below are the last 10 samples (each of size n = 5) taken. The population process standard deviation is 1.64.
