Normal Distribution, Standard Normal Distribution, Probability

1. This week we learned about normal distributions:
a. Using your own words, tell me what the difference is between a normal distribution and a standard normal distribution.
b. Why do we convert values to z scores to find probability?

2. What is the difference between z scores and area in a bell curve?

3. T / F The number associated with the area under the bell curve that falls to the left of the mean or center line is a negative value (read this carefully).
