Question

Consider the conclusion: 70% (±4%) of babies don’t regularly sleep through the night until they are 18 months old.

a. The “(±4)” serves to strengthen the conclusion, thereby making it less likely the conclusion is well-supported by a given sample.

b. The “(±4)” serves to weaken the conclusion, thereby making it more likely the conclusion is well-supported by a given sample.

c. The “(±4)” serves to strengthen the conclusion, thereby making it more likely the conclusion is well-supported by a given sample.

d. The “(±4)” serves to weaken the conclusion, thereby making it less likely the conclusion is well-supported by a given sample.

e. The “(±4)” is generally irrelevant to whether a sample can adequately support this conclusion.

Option-C) The “(±4)” serves to strengthen the conclusion, thereby making it more likely the conclusion is well-supported by a given sample.

Because it gives an error percentage of 4% , so that the actual result may varry between (70-4)% to (70 + 4)%
