- Some notes:
- In class we have only covered margin of error of +/-1.96 SE, which corresponds to the 95% confidence interval. In general, you can do a margin of error of +/- z_{alpha/2} SE, corresponding to a 100(1-alpha)% confidence interval. The size of the margin of error which corresponds to a certain confidence interval is half the lenght of the confidence interval, in the cases we have considered here.
- In class we learned how to do box plots with whiskers and outliers. We extend the whiskers using the 1.5 IQR rule, and then draw in the outliers. An "easy" version of boxplots, extends the whiskers out to max/min, ignoring the outliers. This is what 2a is asking you to do. You can do the side-by-side boxplots by hand.
