4. The standard deviation of the sampling distribution of the sample mean is also called the: a. central limit theorem b. standard error of the mean c. finite population correction factor d. population standard deviation 5. If a random sample of size   n   is drawn from a normal population, then the sampling  distribution of the sample mean  X  will be: 6. If all possible samples of size  n  are drawn from a population, the probability distribution  of the sample mean  X  is called the: 1

### 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.
