PDF-Topic 2: Confidence Intervals and Hypothesis Tests

Module 22 Confidence Intervals for Two Parameters Lecture 224 Confidence Intervals as Hypothesis Tests The foregoing section shows that the computaprovide computational procedures forces of means. 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.
