 * __MTED 493 HW 5 and More...__**

I note that using the Z-Distribution or Inverse-Z (instead of T-Distribution or Inverse-T) seemed to let the hand- calculations align almost perfectly with the automatic Fathom results. You can try this same idea (generating Confidence Intervals and Hypothesis Testing) with Means: For example, I've been playing with the "Mortgage Data", which is on the Wiki, (see [032] ) comparing National Data with a subset (filtering on Washington or California, for instance). I also played with the "Professor Salary" data and even Baseball96 (comparing a filter of SanFrancisco Giants versus all the teams). Anyhow, it's fun to look at the idea we did with Estimating and Testing Proportions, but now with Means. See how the hand-calculations compare with the automatic Fathom results. And I posted a few more supplemental things on this to our Class Wiki.
