A 95% confidence interval is constructed for the true mean. Which statement is correct?
- A
95% of all sample means fall in this interval.
- B
The true mean has a 95% chance of being a particular value.
- Ccheck_circle
If many random samples are taken and CIs constructed, about 95% will contain the true mean.
- D
All future samples will lie in this interval.
Explanation
A 95% CI means: across many repeated samples, about 95% of the constructed intervals will contain the true population mean.
