When sample size increases Group of answer choices

Confidence interval decreases
Confidence interval remains the same
Confidence interval increases
Standard deviation of the sample mean increases

Option A)

Confidence interval decreases

Step-by-step explanation:

If we increase the sample size, then,

The standard error of the interval decrease.If the standard error increase, the margin of error of the interval decrease.If the margin of error decreases, the width of the confidence level decreases, hence, the confidence interval become narrower.

Thus, the correct answer is

Option A)

Confidence interval decreases
