In class students were introduced to z-scores which are number of standard deviations away from the mean. We now have a way of comparing apples to oranges. How far away datum is from the mean tells us whether something is unusual or not. Standardized tests such as the SATs and ACTs are scored based upon z-scores.
The notes are attached and the homework is listed below.
