Part 2

a) Standard deviation of the sampling means =

. 608

ounces (round your response to three decimal places).

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

UCLx = ___ ounces ?(round your response to three decimal? places).

LCLx= ____ ounces ?(round your response to three decimal? places)

C) The control limits for the? R-chart are:

UCLr = ____ ounces ?(round your response to three decimal? places)

LCLr = ____ ounces ?(round your response to three decimal? places)

d) Based on the x overbarx?-chart, is one or more samples beyond the control? limits? Yes/No

Based on the? R-chart, is one or more samples beyond the control? limits? Yes/No
