If Charlene Brewster has times of 8.4, 8.6, 8.3, 8.5, 8.7,and 8.5 and a performance rating of 110%, what is the normaltime for this operation? Is she faster or slower than normal?
Jell Lee Beans is famous for its boxed candies, which are sold primarily to businesses. One operator had the following observed times for gift wrapping in minutes: 2.3, 2.7, 2.4, 2.4, 2.3. The operator has a performance rating of 110% and an
allowance factor of 10%.
The standard time for this gift-wrapping operation =
minutes (round your response to one decimal place).
