In this chapter, we have studied confidence intervals. Carefully read the following statements about confidence intervals:
Once the endpoints of the confidence interval are numerically fixed, the parameter in question (either µ or p) does or does not fall inside the “fixed” interval.
A given fixed interval either does or does not contain the parameter µ or p; therefore, the probability is 1 or 0 that the parameter is in the interval.
Next, read the following statements. Then discuss all four statements in the context of what we actually
Nontrivial probability statements can be made only about variables, not constants.
The confidence level c represents the proportion of all (fixed) intervals that would contain the parameter if we repeated the process many, many times.
