) Determine Normal Time . Answer in 4 decimal places b) What is the standard time? Round up answer in 2 decimal places. c) If the worker's performance during actual production is 125% on all manual elements for seven hours worked on an eight-hour shift, how many units will be produced? Round up answer in integer value. d) Determine the worker's efficiency (in percentage). Answer in 2 decimal places
A process has seven elements composed of combination of worker and machine. Elements A, B, D, and F are worker-controlled while elements C and E are machine controlled. Element G is a worker-controlled irregular element performed every five cycles Machines are idle during elements A, D, and G. Two units are produced every cycle. Below are the observed time (in minutes) and performance rating of each element.
| Work Element | Observed Time (in minutes) | Performance Rating |
| A | 0.75 | 115% |
| B | 1.20 | 120% |
| C | 1.40 | N.A. |
| D | 1.05 | 90% |
| E | 1.25 | N.A. |
| F | 1.20 | 105% |
| G | 1.60 | 85% |
