Yelp Dog Food produces specialized dog foods in 1-pound packages. The amount of dog food in each package should be 1 pound, and Yelp has determined that the standard deviation of the machine filling these packages is half an ounce, and the confidence interval is 14.85% (2= 1872). In order to confirm that the machine is operating properly, Yelp takes 16 sample bags every hour and weighs them.

Other things remaining the same, and assuming that X is smaller than USL and larger than LSL, if the standard deviation (σ) of the process increases, process capability index (Cpk) of the process will: Stay the same Will always increase Will always decrease Will sometimes increase
This exercise contains only parts a and b. a) For the given data, the x= ____ hours (round your response to three decimal places). For the given data, mean range =_____hours (round your response to two decimal places). With z=3, the control limits for the mean chart are: UCLx= ____hours (round your response to three decimal places). LCLx=____hours (round your response to three decimal places). The control limits for the range chart are: UCLR=____hours (round your response to two decimal places). LCLR=h____ours (round your response to two decimal places). With these limits established, West now takes 5 more hours of data, which are shown in the following table. Calculate the mean and range for each hour that the sample data is taken. (Enter your responses for the mean to…
Cpk can never be higher than Cp. T or F Non-parametric analysis is usually used for non-ratio and non-interval data. T or F Parametric analysis is stronger, better chance of not having a type II error, than non-parametric analysis T or F
A sales completion team, aiming to reduce the shipment time of urgent orders, studies the current process and finds that the current shipment time has a mean of 4 days with a standard deviation of 1.5 days. Industry expectations are for urgent shipments to be delivered between 1 and 5 days.(1) What is the current process capability Cpk? Please keep 4 decimal places for your answer
A manager wanted to predict how much rework time would result from taking a manufacturing line from producing 8 hours a day to 24 hours a day. The manager carefully analyzed three years of performance from manufacturing lines that operated 8 hours a day to make the prediction. The manager is at risk of making what type of error? a Data overfitting error. b Extrapolation beyond the range error. c Outlier error. d Either a type I or type II error.
The mean service time (x¯) of a physician is 25 minutes with a standard deviation (σ) of 1 minute. Upper specification limit (USL) is 30 minutes, whereas lower specification limit (LSL) is 20 for this process. What is the process capability ratio (cp) for this process? Is the process capable? Cp=1, barely capable Cp=1.5, capable Cp=1, not capable Cp=1.67, not capable Cp=1.67, definitely capable
day, a FedEx competitor processes approximately 70,000 shipments. Suppose that they use the same Service Quality Index as FedEx and identified the following numbers of errors during a five-day week (see the “FedEx: Measuring Service Performance” box): These values are hypothetical and do not reflect any real company’s actual performance. Complaints reopened: 125 Damaged packages: 18 International: 102 Invoice adjustments: 282 Late pickup stops: 209 Lost packages: 2 Missed proof of delivery: 26 Right date late: 751 Traces: 115 Wrong day late: 15 Compute the Service Quality Indicator by finding the weighted sum of errors as a percentage of total shipments.
Suppose that you have a four-sided die that is equally weighted (i.e. equal chance of any of the four sides landing face up). The four values on the die are [12.5968, 2, -2 and -12.5968] . If we roll the die 81 times, record the average, and repeat this process a total of 100 times, what does the central limit theorem predict will be the mean of the set of averages? a) 0 b) 12.59 c) 1.23 d) 5.72
Process Capability (Cpk and Cp) The operations manager of an insurance claimsprocessing department wants to determine the claims-processing capability. Claims usually take a minimum of four days to handle. The company has a commitment to handle all claims within 10 days. On average, claims are processed in eight days and processing has a standard deviation of one day.a. Compute Cp and Cpk for the claims-processing department. Based on these computations, should the claims department improve its process?b. Using the same data, recompute Cpk, but use an average claims-processing time of seven days instead of eight days.c. Using the original data, recompute Cpk, but use a standard deviation of 2/3 of a day. Which change made the most improvement—the change in mean in part b or the change in standard deviation? Can you explain the results?
