Answer: The 95% confidence interval to estimate the population mean describes a range of values that a person can be 95% sure that it contains the population mean.
Explanation:
A 95% confidence interval for population mean (
) is an interval on which a person can be 95% confident that the true population mean lies in it.
i.e. The probability that it contains the true population mean is 95%.
i.e. P( Sample mean- margin of error <
< Sample mean + margin of error) = 0.95.
