What does it mean if a confidence interval does not contain the true population mean?

How do researchers determine if a certain value is plausible based on confidence intervals?

What is the role of sample size in determining the reliability of a confidence interval?

Discuss the trade-off between accuracy and precision in confidence intervals.
