Before attempting the exercise, click to read the PEI Potato Purveyors case study. What are the desired mean and standard deviation? A. 47.51 and 1.2 B. 50.0 and 1.2 C. 48.8 and 2.45 D. 51.2 and 2.45 Throughout the year in 2021, Isabella Garcia had been receiving random complaints from various customers. Isabella is the operations manager at PEI Potato purveyors Inc., and the complaints she received surrounded the fact that the quantities of product delivered were inconsistently deviating from the amounts specified on the packaging. This would require isabella to fully investigate this matter. Isabella ordered the supervisors to undertake a random sample weight measurement of 50 containers, each of which historically held 50 klos of potatoes, with an acceptable standard deviation of 1.2 kilos. Upon closer examination, isabelia discovered that the potato containers in this random sample weighed on average 47.51 kilos, well outside the acceptable standard deviation. Isabelia was deeply concerned for several reasons. Why did she recelve only random and not consistent complaints? Did no one notice, or was this an inconsistent problem? Why had the weight changed over the years while using the same container? Further invesugation informed Isabelia of soveral contributing factors. The PEI Potato Purveyors' typical customer. would be a food processing company that makes large quantities of french fries, mashed potatoes, hash browns, and to on. The container that is used is too heavy to lift and is normally loaded and unloaded by forklift, and in some cases the entire quantity is dumped into a processing machine. Some machines would process 50 kilos of potatoes at one fime. If the inpot was short on quanuty. so too wouid be the output, and this would bo noticeable to the food processing immediately ordered a credit for those that brought this situation to her attention. But isabeila stiul had to uncover the root cause and rectify it. What was different now than before that could affect the woight? It tumed out that although they were using the same containers, they were using a different lid that dipped into the container somewhat. In order to fit the lid properly, employees would remove several potatoes from the container rather than push down and damage them. Also, it was discovered that they had a new supplier of potatoes container rather than push down and damage them. Also, it was discovered that they had a new supplier of potatoes added to their list and this farm produced a new type of potato that was large and irregular in shape. This caused more air space in the container, and thus less weight. Ultimately, a new container lid that resembled the original style would be required, as well as a new sorting mechanism for the large irregular shaped potatoes. Isabella wanted to determine if different shifts in the plant were dealing with these issues in a different way and arranged for six random weight measurements per hour to be taken throughout the day.
