PPT-Section 7.8 Confidence Intervals

Special Topics A 95 Confidence Interval Now in plain English What this is saying is that a 95 confidence interval is an interval created to estimate what where the true parameter might be. Remember we saw The sample proportion will differ from the population proportion by more than the margin of error less than 5 of the time The Margin of Error for a sample of size n is 1 n Suppose we wanted to estimate a Population Mean rather than a Robin H.
