By Olivia Mah
We have a (relatively) short video today!
We will continue with Ch 21. Our focus is on constructing confidence intervals to estimate difference between two population means.
Instructions
- There are 2 confidence interval problems in this lab work (not from the book).
-

We are 99% confident that the population mean ______ for _____
is smaller than that of _____
by an amount that might be as small as ………
or is larger than that of _____
by an amount that might be as large as…….. .
- The video explains the concept and shows you how to do the lab work:
