If the US could make 14 stereos/hr or 7 cars/hr, this is a ratio of 2 stereos/1 car, or 1 stereo/0.5 cars. Therefore the US opportunity cost of producing 1 stereo is 0.5 car of half a car.
If China (or Japan? given the question in #2) makes 15 stereos/hr or 5 cars/hr, this is a ratio of 3 stereos/1 car, or 1 stereo/0.33 cars.
The difference in the average age of the sample and the population is probably due to sampling error
<h3>What is sampling error?</h3>
The sampling error in a statistical data is simply an error that arises when a sample that represents the population is not properly selected or analyzed
From the question, we have the following parameters:
-- the sample average
-- the population average
Notice that:
i.e. sample and the population averages are not equal.
This difference is often as a result of sampling error
