Suppose that you take 1000 simple random samples from a population and that, for each sample, you obtain a 95% confidence interv
Bogdan [553]

Using the interpretation of a confidence interval, it is found that approximately 950 of those confidence intervals will contain the value of the unknown parameter.

A x% confidence interval means that we are x% confident that the population mean is in the interval.

  • Out of a large number of intervals, approximately x% will contain the value of the unknown parameter.

In this problem:

  • 95% confidence interval.
  • 1000 samples.

0.95 x 1000 = 950

Hence, approximately 950 of those confidence intervals will contain the value of the unknown parameter.
