6. A critical dimension of the service quality of a deposit collection booth is the waiting time of atransaction to get money from the employee. Periodically, random samples of four customer aremeasured for waiting time. The results of the last five samples are in the following table:Sample Time (sec) from Four Customers1 525 510 495 5142 512 520 508 5243 505 458 504 5054 450 495 521 5125 498 510 480 521Required:i. Assuming that the management is willing to use three-sigma control limits and using onlyhistorical information of the standard deviation of the process distribution is 6.85 thatcontained in the five samples, show that the ATM Booth waiting time is in statistical control.ii. Suppose that the standard deviation of the process distribution is 6.85. If the specification forthe waiting time are 510±35sec., is the process capable? Why or why not? Assume Threesigma performance is desired by the management.

Study B: The decoy effect is the phenomenon that an additional but worse option can boost the appeal of an existing option. In order to get workers at food-processing factories in China to comply with hygiene standards (i.e., using hand sanitizer every hour), researchers manipulated whether there were additional options to the standard and convenient spray bottle provided to each employee. Workers in different rooms were randomly assigned to have just the standard spray bottle, or the standard spray bottle and an inconvenient squeeze bottle. Quality control personnel kept track of hand sanitizer use (weighing the bottles before and after each shift) and sanitary condition (sample wipes assessing the number of bacteria on hands). Neither the employees or quality control personnel were aware of the experiment or its hypothesis. The researchers found that when a decoy was present, workers used more sanitizer and were more likely to pass hand sanitary tests. In this example, it was…
