Today we discussed Section 9.1 which concerned Confidence Intervals (CI) for population mean. It is important to know
1. how to calculate CI using the TI83/84 (and not by hand);
2. how confidence level and sample size affect CI;
3. how to interpret what a CI tells us about the parameter.
We will do many more calculations of CI over the next several class periods. Also, on Monday, we will discuss Sections 8.2, 9.2 and 9.3.
There is no homework due on Tuesday.
