PPT-Section 8.1 Confidence Intervals: The Basics

Section 81 Confidence Intervals The Basics After this section you should be able to INTERPRET a confidence level INTERPRET a confidence interval in context DESCRIBE how a confidence interval gives a range of plausible values for the parameter. 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.
