Of the 10,000 clocks from which the sample was chosen, about how many clocks are probably not defective?
tamaranim1 [39]

The number of clocks that are not defective is an illustration of proportions

Of the 10000 clocks, 9250 are probably not defective

<h3>How to determine the number of clocks that are not defective?</h3>

From the complete question, we have the following parameter:

15 out of 200 clocks are defective

The above means that the number of clocks that are not defective is:

Not defective = 200 - 15

Not defective = 185

Express as percentage

Not defective = 185/200

Not defective = 92.5%

In 10,000 the number of clocks that are not defective would be:

Not defective = 92.5% * 10000

Not defective = 9250

Hence, 9250 of the 10000 clocks are probably not defective
