1. 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?
