The use of preservatives by food processors has become a controversial issue Suppose two preservatives are extensively tested and determined safe for use in meats. A processor wants to compare the preservatives for their effects on retarding spoilage. Suppose 16 cuts of fresh meat are treated with preservative I and 16 are treated with preservative II, and the number of hours until spoilage begins is recorded for each of the 32 cuts of meat. The results are summarized in the table below. 4 Preservative I Preservative II X-96 54 hours 51-18.8 hours X106.4 hours 5-10.1 hours Suppose ax = 0.01. Which of the following represents the result of the relevant hypothesis test? 1) The null hypothesis is not rejected. 2) The null hypothesis is rejected. 3) The alternative hypothesis is rejected. 4) Insufficient information exists on which to make a decision.

Hi, can someone help me with this question please?
A manufacturer of packaging for companies that produce breakfast cereals is considering alternatives regarding the process it uses to pre-process carton paper used to make the packaging. Historically, the company has been using equipment which cuts raw carton paper received from its various suppliers. This cut paper is further painted and assembled into a box shape by two other pieces of equipment. Recently, however, most of its customers began requesting that certain design elements be pressed into the packaging, giving the packaging more visual appeal. The customers were willing to pay more for the added service, making it particularly lucrative for the firm to have incorporate this possibility into its packaging offerings. Managers believed that the existing equipment would be able to handle the new process with certain modifications. In addition to modifying the existing equipment, the company two other alternatives. All alternatives will be able to produce the desired result, will…
Mary Green, who works as a manager at the Sea Breeze Restaurant, is analyzing service problems that are increasingly causing owners' concerns. She found out that the customers often decline the menu items ordered because they don't like the substitutes for traditional ingredients, for example, they decline chicken dishes advertised as made from chicken breast but made from chicken thighs instead. The returns of well-prepared dishes to the kitchen increase waste and, therefore, cut into profits. Which of the following control points is likely to be the focus of the initial corrective action? a. Purchasing of food b. Issuing of food c. Preparing of food d. Serving of food
Cheyenne Landscaping plants grass seed as the basic landscaping for business campuses. During a recent month, the company worked on three projects (Remington, Chang, and Wyco). The company is interested in controlling the materials costs, namely the grass seed, for these plantings projects.In order to provide management with useful cost control information, the company uses standard costs and prepares monthly variance reports. Analysis reveals that the purchasing agent mistakenly purchased poor-quality seed for the Remington project. The Chang project, however, received higher-than-standard-quality seed that was on sale. The Wyco project received standard-quality seed. However, the price had increased and a new employee was used to spread the seed.Shown below are quantity and cost data for each project. Actual Standard Project Quantity Costs Quantity Costs Total Variance Remington 530 lbs. $1,272 440 lbs. $1,100 $172 U Chang 400…
A production line operation is designed to fill cartons with laundry detergent to a mean weight of 32 ounces. A sample of cartons is periodically selected and weighed to determine whether underfilling or overfilling is occurring. If the sample data lead to a conclusion of underfilling or overfilling, the production line will be shut down and adjusted to obtain proper filling. a. Formulate the null and alternative hypotheses that will help in deciding whether to shut down and adjust the production line. b. Comment on the conclusion and the decision when H0 cannot be rejected. c. Comment on the conclusion and the decision when H0 can be rejected.
AccuSound Corporation manufactures printed circuits for stereo amplifiers. A common product defect is a "drift" caused by failure to maintain precise heat levels during the production process. Rejects from the 100 percent testing program can be reworked to acceptable levels if the defect is drift. However, in a recent analysis of customer complaints, Marie Allen, the assistant controller, and the quality control engineer determined that normal rework does not bring the circuits up to standard. Sampling showed that about half of the reworked circuits will fail after extended amplifier operation. The incidence of failure in the reworked circuits is projected to be about 10 percent over five years.3. What should Marie Allen do?
Flextron’s controller, Vince Chadwick, tells Marta Suarez, the management accountant responsible for Job No. M102, the following: “This was an unusual job. I think all 6,000 spoiled units should be considered normal.” Suarez knows that the work involved in Job No. M102 was not uncommon and that Flextron’s normal spoilage rate of 2% is the appropriate benchmark. She feels Chadwick made these comments because he wants to show a higher operating income for the year. a. What should Suarez do in response to Chadwick’s comment?
(Prepared from a situation suggested by Professor John W. Hardy) Lone Star Meat Packers is a major processor of beef and other meat products. The company has a large amount of T-bone steak on hand, and it is trying to decide whether to sell the T-bone steaks as they are initially cut or to process them further into filet mignon and the New York cut If the T-bone steaks are sold as initially cut, the company figures that a 1-pound T-bone steak would yield the following profit Selling price ($2.00 per pound) Less joint costs incurred up to the split-off point where T-bone steak can be identified as a separate product Profit per pound $ 2.00 1.30 $ 0.70 If the company were to further process the T-bone steaks, then cutting one side of a T-bone steak provides the filet mignon and cutting the other side provides the New York cut. One 16-ounce T-bone steak cut in this way will yield one 6-ounce filet mignon and one 8-ounce New York cut, the remaining ounces are waste. It costs $0.17 to…
Richins Company is considering the acquisition of a computerized manufacturing system. The new system has a built in quality function that increases the control over product specifications. An alarm sounds whenever the product falls outside the programmed specifications. An operator can then make some adjustments on the spot to restore the desired product quality. The system is expected to decrease the number of units scrapped because of poor quality. The system is also expected to decrease the amount of labor inputs needed. The production manager is pushing for the aquisition because he believes that productivity will be greatly enhanced - particularly when it comes to labor and material inputs. Output and input data follow. The data for the computerized system are projections. Current System Computerized System Output (units)…
