Objectives for the Second Test (Chapters 7-12) Chapter 7 1. Students should be able to define the distribution of sample means and, for a specific sampling situation, describe the distribution by identifying its shape, the expected value of M, and the standard error of M. 2. Students should understand that each sample mean, M, has a location in the distribution of sample means that can be described by a z-score equal to M μ z = ───── where σ M is the standard error of M σ M 3. Using the distribution of sample means, z-scores, and the unit normal table, students should be able to determine probabilities corresponding to specific sample means. Chapter 8 1. Students should understand the logic of hypothesis testing. 2. Students should be able to state the hypotheses and locate the critical region. 3. Students should be able to conduct a hypothesis test using a z-score statistic and make a statistical decision.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
