Question

What does "99% confidence" mean in a 99% confidence inveral?

A) If 100 different confidence intervals are constructed, each based on a different sample size n from the same population, then we expect 99 of the intervals to include the parameter and 1 to not include the parameter.

B) the confidence interval includes 99% of all possible values for the parameter.

C) The probability that the value of the parameter lies between the lower and upper bounds of the interval is 99%. The probability that it does not is 1%.

D) The value of the parameter lies within 99% of a standard deviation of the estimate.

Explanation / Answer

The best definition for confidence is given in option A)

If 100 different confidence intervals are constructed, each based on a different sample size n from the same population, then we expect 99 of the intervals to include the parameter and 1 to not include the parameter.
