We have a (relatively) short video today!

We will continue with Ch 18. 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).
  • For the 2nd question, follow the format below for the conclusion:

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:

Ch 18 Two-sample confidence interval

• Submit your lab work as one single PDF file to Canvas before the due date.
