If we know that out of 100 sampled wires, 4 were defective, we can use that ratio to estimate how many defective wires we should expect out of 750 wires produced in one hour.

The ratio of sampled wires to defective wires is 100:4. If we apply that ratio to 750 wires produced, we can set up a proportion:

100/4 = 750/x

Cross-multiply:

100x = 4 * 750

100x = 3000

Divide both sides by 100:

x = 30

So the manufacturer should expect 30 wires to be defective out of the 750 produced in one hour. That's option A, my friend! Keep an eye out for those "shocking" wires!

Step 1: Calculate the proportion of defective wires in the sample.

The sample contains 100 wires, and 4 of them are defective. We can write this as a fraction:

Defective wires / Total wires = 4 / 100 = 0.04

Step 2: Use the proportion to estimate the number of defective wires in the production batch.

If the proportion of defective wires in the sample is 0.04, we can assume that it applies to the entire production batch. Therefore, we multiply the proportion by the total number of wires produced in one hour:

0.04 * 750 = 30

Therefore, the manufacturer should expect around 30 defective wires in the production batch.

The correct answer is option A. 30.
