Today, if we have a little more time, we will startPacket 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.
Let's remind ourselves about the distribution of $\hat{p}$:
Now in this case we don't have $p$. We want to find $p$. So how do we proceed? That's the subject of this packet.
