Happy Thanksgiving! (Almost)!

 

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). To avoid confusion, please use the following notations:

 

• • • Question #1:
      • • (1) denotes the male population, (2) denotes the female population.  The  sample estimate that you use is:  x1 – x2
    • Question #2:
      • • (1) denotes the control population, (2) denotes the Ancy population.  The  sample estimate that you use is:  x1 – x2

 

• 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.
