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.

a) Standard deviation of the sampling means =

. 7335.7335

ounces (round your response to three decimal places).

b) With z =

3,

the control limits for the mean chart are:

UCLx

=

nothing

ounces (round your response to three decimal places)

Standard deviation of the sampling means =

nothing

ounces (round your response to three decimalplaces).b) With z =

3,

the control limits for the mean chartare:

UCL Subscript x overbarUCLx

=

nothing

ounces (round your response to three decimalplaces).

LCL Subscript x overbarLCLx

=

nothing

ounces (round your response to three decimalplaces).

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

UCL Subscript Upper RUCLR

=

nothing

ounces (round your response to three decimalplaces).

LCL Subscript Upper RLCLR

=

nothing

ounces (round your response to three decimalplaces).d) Based on the

x overbarx-chart,

is one or more samples beyond the control limits?

Yes

No
