Question

A rum producer monitors the position of its label on the bottle by sampling four bottles from each batch. One quantity measured is the distance from the bottom of the bottle neck to the top of the label. The process mean should be μ = 1.8 inches. Past experience indicates that the distance varies with σ = 0.13 inch. (a) The mean distance x for each batch sample is plotted on an x control chart. Calculate the center line and control limits for this chart. (Round your answers to three decimal places.)

CL =1.8 in correct

LCL =1.605 in correct

UCL = 1.995 in correct

PLEASE HELP WITH THE 2 ITEMS BELOW THAT ARE WRONG

(b) The sample standard deviation s for each batch's sample is plotted on an s control chart. What are the center line and control limits for this chart? (Round your answers to four decimal places.)

CL = 0.1037in WRONG

LCL = 0 in Correct

UCL = 0.23504in WRONG
