Quadrupling the sample size while holding the confidence coefficient fixed will not affect the width of the confidence interval.

<h3>What is Confidence coefficient?</h3>

This is defined as the confidence level in the form of a proportion rather than as a percentage.

Holding it fixed means no matter how the sample size is varied, the width of the confidence interval won't be affected. This is therefore the reason why quadrupling the sample size will have no effect and is therefore the correct choice.

The bacteria cell wall

Since the drug targets only the structures that bacteria have, the target structure should be cell wall because human or animal cells do not have cell walls but cell membrane whereas bacteria cells have cell walls. So targeting cell walls would make the drug effective on bacteria while not affecting the animal cell thus there will not be any side effect of the drug on the animal.
