If a distribution is normal with


μ

= 60 and

σ

= 15, what is the
z-score of 75?

2.



If a distribution is normal with


μ

= 60 and

σ

= 15, what is the
z
score of 40?

3.



How can the normal distribution be used to test hypotheses about populations? Also, how might you surmise that you can use this logic to test a hypothesis such as caffeine improves memory in the caffeine study that I reference in my lectures?
