A confidence interval is computed from a sample selected from a population. Based on the concept of confidence interval, please answer the following question.

There are two simple random samples selected from the same population. The sample with small sample sizes will tend to have large margins of error.

Select one:

True

False

Solution

In the margin of error sample size always comes into denominator. So when we increase the sample size (all other things remain constant) margin of error decreases and when decrease the sample size (all other things remain constant) margin of error increases .

So given statement is true.
