In a random sample of 400 watches, 3 are defective. Out of a total of 10,500 watches, how many would you expect to be defective based on this sample data?
Using proportions, we can set up the following equation:
3/400 = x/10,500
Solving for x, we get:
x = (3/400) * 10,500
x = 78.75
Therefore, based on this sample data, we would expect approximately 78.75 watches out of 10,500 to be defective. However, it's important to note that this is just an estimate and the actual number of defective watches may differ.
