Question: Which one of the following is the most appropriate definition of a 99% confidence interval?

  1. 99% of the time in repeated samples, the interval would contain the estimated value of the null hypothesis
  2. 99% of the time in repeated samples, the interval would be different from the estimated value of the parameter
  3. 99% of the time in repeated samples, the null hypothesis will not be rejected when it was false
  4. 1% of the time in repeated samples, the interval would not contain the true value of the parameter
  5. 99% of the time in repeated samples, the interval would contain the true value of the null hypothesis
  6. 99% of the time in repeated samples, the null hypothesis will be accepted when it was false
  7. 99% of the time in repeated samples, the null hypothesis will be rejected
  8. 99% of the time in repeated samples, the interval would contain the estimated value of the parameter
  9. 99% of the time in repeated samples, the interval would contain the true value of the parameter
  10. 99% of the time in repeated samples, the interval would not contain the true value of the null hypothesis

Our answer: I. 99% of the time in repeated samples, the interval would contain the true value of the parameter Source quote machine-checked (exact quote)

“That is, for a 95 % confidence interval, if many samples are collected and the confidence interval computed, in the long run about 95 % of these intervals would contain the true mean.”
