B) A larger sample size will not affect the size of the confidence interval.
C) A smaller sample size will not affect the size of the confidence interval.

Confidence Interval

A confidence interval is a range of values, derived from sample data, that is likely to contain the true value of an unknown population parameter with a specified level of confidence.

Sample Size

The number of participants, observations, or data points collected in a study, important for ensuring the statistical validity and reliability of the research findings.

Larger Sample Size

A methodological strategy in research that involves increasing the number of participants to enhance the reliability and validity of the study's outcomes.
