The task involves use of a ruler, square, and portable electric saw to mark and cut the "notch" in a rafter (a standard carpentry task of home construction). In a preliminary study, he observed one of his workers performing this task five times. The observations were made in an air-conditioned, well-lit training facility, at ground level, with all tools and equipment clean and readily available. Observation: 1 2 3 4 5 Task time (seconds): 82 74 80 83 76 a. What is the actual average time for this task? b. What is the normal time for this task if the employee worked at a 20% faster pace than is typical for adequately trained workers? c. What is standard time for this task if allowances sum to 14%? d.

- Explain Time Fencesarrow_forwardDefine a simultaneous motion chart?arrow_forwardSADI Limited is a manufacturing company with several branches across the Ghana. The company has been facing several issues regarding turnover of employees for the past five years which has resulted in the low sales, reduced profit and the inability of the firm to meet it strategic objectives. In addition, the company is faced with severe competition from other firms in the industry it operates. You have been engaged as a Human Resource Management consultant to help resolve these concerns.

As the HRM consultant for SADI Limited what recommendations will you give to enable the firm ensure that the approaches used in choosing candidates for the job predicts the right candidates who will better fit into job roles and contributes significantly to the success of the firm.arrow_forward
- What are motion study principles? How are they classified?arrow_forward15-19 A new president at Big State University has made student satisfaction with the enrollment and registration process one of her highest priorities. Students must see an advisor, sign up for classes, obtain a parking permit, pay tuition and fees, and buy textbooks and other supplies. During one registration period, 10 students every hour are sampled and asked about satisfaction with each of these areas. Twelve different groups of students were sampled, and the number in each group who had at least one complaint is as follows: 0, 2, 1, 0, 0, 1, 3, 0, 1, 2, 2, 0. Develop upper and lower control limits (99.7%) for the proportion of students with complaints.arrow_forwardIn recent years more people have been working past the age of 65. In 2005, 27% of people aged 65-69 worked. A recent report from the Organization for Economic Co-operation and Development (OECD) claimed that the percentage working had increased (USA Today, November 16, 2012). The findings reported by the OECD were consistent with taking a sample of 600 people aged 65-69 and finding that 180 of them were working. a. Develop a point estimate of the proportion of people aged 65-69 who are working (to 2 decimals). b. Set up a hypothesis test so that the rejection of Ho will allow you to conclude that the proportion of people aged 65-69 working has increased from 2005.
