Question: 1 f samples of 100 for a process are taken...

1. f samples of 100 for a process are taken and p is 0.15, the upper and lower control limits for a 3-sigma p-chart are

a	UCL = 0.322, LCL = 0.000

b	UCL = 0.190 , LCL = 0.010

c	UCL = 0.257, LCL = 0.043

d	UCL = 0.045, LCL = 0.005

2.

In an Excel spreadsheet for a p-chart, if the total number of defectives for 20 samples of 100 observations each is in cell F26, the Excel formula for p is

a	=((F26)*(20))/100

b	=((F26)*(100))/20

c	=(F26)/(20)

d	=(F26)/((20)*(100))

3. In an Excel spreadsheet for a c-chart, if the population process average for 20 samples, c, is in cell H4, the Excel formula for the upper control limit is

a	=H4+SQRT(3*H4)

b	=H4+3*SQRT(H4)

c	=H4+3*SQRT((H4*(1-H4))/(100))

d	=H4+3*SQRT(H4/20)
