Error in true mean = +/-Z*

Where; Z=2.58 at 99% confidence interval, s= sd = 0.25 hours, n=sample population = 60 refrigerators
Therefore;
Margin of error = +/-2.58*

= 0.0832 hours

Explanation:
INNOVATION: When workers are set specific tasks, that is their pure focus. So it becomes easier to see pitfalls in the existing process. Doing the same task each day makes it easier to analyse areas for improvement. It takes up more of the brains processing power, so it is at the forefront of a workers mind.
HIGHER WAGES: It must be said that not all the productivity gains are necessarily passed on to the consumer. A proportion may go to profits, whilst some may go to higher pay for employees.
CHEAPER PRODUCTS: It must be said that not all the productivity gains are necessarily passed on to the consumer. A proportion may go to profits, whilst some may go to higher pay for employees.
PRODUCTIVITY: When workers focus solely on a specific task, they can master it quicker and more efficiently. In turn, workers become more productive.
EFFICIENT MASTERY: Without the division of labor, mastery of a skill takes much longer. This is because a workers attention is spread across many areas.
For instance, it would be difficult to master a language if you are also trying to learn the piano, engineering, CSS, and economics. So, the division of labor allows the worker to focus and master a specific part of the process, which helps them learn it faster.
