Question

The time that it takes a worker to finish a particular assembly line task is normally distributed, with a mean of 32 seconds and a standard deviation of 10 seconds. The slowest 10% of workers (those with the slowest 10% of times) will be required to spend the weekend training, to try to improve their times. What is the minimum speed a worker must achieve to escape the weekend training?
