Practice using the z-formula!
6.4: Introduction to the z table
Our first critical value table!
6.5: Practice Using the z Table
Practice using the z-table; now we're getting somewhere!
6.6: Predicting Amounts
Can you do more with z-scores than find probabilities?
6.7: Summary of z Scores
If you're still not sure what a z-score is, or why it might matter, check out this summary.
