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

An airline operates a call center to handle customer questions and complaints. The airline monitors a sample of calls to help ensure that the service being provided is of high quality. Ten random samples of 100 calls each were monitored under normal conditions. The center can be thought of as being in control when these 10 samples were taken. The number of calls in each sample not resulting in a satisfactory resolution for the customer is as follows. 4 4...
A sandwich shop owner takes a daily sample of six consecutive sandwich orders at a random time during the lunch rush and records the time it takes to complete each order. Past experience indicates that the process mean should be μ = 80 seconds, and the process standard deviation should be σ = 22 seconds. Calculate the center line and control limits for an x control chart. (Round your answers to two decimal places.) CL = sec LCL = sec...
