Suppose a 95% confidence interval for μ turns out to be (1,000,2,100) .What does it mean to be 95% confident?

A) In repeated sampling,the population parameter would fall in the resulting interval 95% of the time.
B) 95% of the observations in the entire population fall in the given interval.
C) 95% of the observations in the sample fall in the given interval.
D) None of these choices.

Confidence Interval

An expanse of values, culled from sample statistics, believed to hold the value of a cryptic population parameter.

Population Parameter

A numerical value that summarizes a characteristic of an entire population, such as its mean or standard deviation.

Observations

Observations are the act of watching or noticing something or data collected during such activities, often used as the basis for scientific research or studies.
