Production Manager Nhu asked her assistant, Trinh, to check the capability of a machinery used in the process. Trinh obtained 20 random samples of 16 pieces each. The results of those samples are shown in the following table. After she analyzed the data, she concluded that the process was capable based on a specification width of 1.56 cm. Nhu was quite disappointed when she heard this. She had hoped that with the introduction of the new product her operation could run close to full capacity…arrow_forwardNidec Sankyo Vietnam Corporation, founded in 2005, over 14 years of operation, Nidec Sankyo Vietnam Corporation has become a supplier for many major companies such as Canon, Mitsubishi, Toto, Brother, Kyocera, etc. Some of the company's outstanding products are motors and drives, card readers, plastic injection processing, music boxes, JIG, hot stamping molds, steel molds, metal molds, electronic components, computer accessories, molding products, etc. The company was about to lunch a new product.

(1987). To process income tax forms, the IRS first sends each form through the data preparation (DP) department, where information is coded for computer entry. Then the form is sent to data entry (DE), where it is entered into the computer. During the next 3 weeks, the following quantities of forms will arrive: week 1, 40,000; week 2, 30,000; and week 3, 60,000. All employees work 40 hours per week and are paid $500 per week. Data preparation of a form requires 15 minutes, and data entry of a form requires 10 minutes. Each week, an employee is assigned to either data entry or data preparation. The IRS must complete processing all forms by the end of week 5 and wants to minimize the cost of accomplishing this goal. Assume that all workers are full-time employees and that the IRS will have the same number of employees each week. Assume that all employees are capable of performing data preparation and data entry. Determine how many workers should be working and…arrow_forwardThe College of Engineering of a State University gives an entrance exam to incoming freshmen. Those who got scores equal or higher than the set passing are accepted in the College. The average score of the incoming freshmen was 80% before the implementation of K to 12 education system. Due to this implementation, the entrance exam was suspended for two years and it is thought that the quality of the first year students had diminished. However, with the vision, mission, goals and objectives of the University and the College towards quality education, the Dean wants to determine if the quality of freshmen students has changed. He wants to know if it has improved or diminished so a small random sample of 15 freshmen students and administers the same entrance exam. The average score is found to be 83% with a standard deviation of 5%. Determine whether the quality has changed using 1% level of significance.arrow_forward

After a hearing, the agency determined that Bruce had no aptitude for math and that he would not receive any funding. Bruce, however, was not discouraged. He told his friend Laura, who just graduated from law school, that he would simply appeal the decision to federal court, have the judge do a fresh review, and provide additional information to the judge regarding his math aptitude that the agency did not have. He feels certain that he will win at the federal court level. Assuming the decision by the administrative agency was a factual finding, what should Laura tell Bruce regarding the standard of review the administrative agency will likely apply?That the agency will likely apply a de novo, or new, review.That the agency will likely apply an arbitrary and capricious standard in any review.That the agency will likely apply a substantial evidence…arrow_forwardThe Center for Information Technology at State Univer-sity has outgrown its office in Bates (B) Hall and is mov-ing to Allen (A) Hall, which has more space.
