Question

Confidence Interval: What is the 95% confidence interval to estimate the population mean?

Answer 1

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.

Step-by-step explanation:

A 95% confidence interval for population mean ($\mu$) 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 < $\mu$ < Sample mean + margin of error) = 0.95.
