This is the worksheet that goes with HW#2:
18 Worksheet - Sampling Distributions with Means

EXTRA BONUS STUFF: (stop here unless you're bored and have some time to burn)
If you are extra curious about how the distribution of means approaches a Normal distribution as the sample size increases, here is a video that attempts to demonstrate. Warning: We did NOT go into this level of detail in class and it's not a fun watch.
Video: Sampling Distributions for Means (13m 50s)

And here is a link to the sampling distributions simulation app used in the video:

Here are the notes from class for W/Th, Jan 7/8 (please note that B-day is ahead of A-day for the 2nd semester):

1. if you were in periods 1, 6, 7, or 8, I mistakenly told you to do #10 instead of #18... but that's okay as well [↩]
