- Reminder: stash your rectangles.
- You have a quiz today.
- We have a test coming up next week through confidence intervals
(Packet 5). So it will be the complete story of $p$!
- You have a new IMath assignment due next Tuesday at 5:00 p.m.
There's some StatCrunch on it, so let's take a look at that question in IMath.
Hint on IMath: use the "print" form to see what your answers were in your most recent submission. So you can see what you put, and perhaps figure out why it was wrong.
- We finished up talking about errors in hypothesis testing,
(sometimes we make mistakes while
testing):
We also started Packet 5: confidence intervals for a proportion.
- Today we continue Packet 5, which
has two major objectives:
- estimate parameter $p$ using statistic $\hat{p}$, with given confidence, and
- discover the sample size needed to estimate $p$ with given confidence.
