1.How does the SD relate to the standard error in terms of the formula

for the standard error? (2 points)

2.(2 pts) A population has a = 80 and = 10. A sampling distribution from that population, based on samples of n = 64, will have a M of ________ and a standard error of ___________. (this question is as simple as it looks!)

3.Explain the relationship between distribution of sample means and normalitythat is, under what circumstances is the distribution of sample means normal? (hint: look at the central limit theorem...) (2 points)

4.(2 pts) A sample of n = 144 scores is selected from a population with = 60 and = 9. On average, how much error is expected between the sample mean and the population mean?

(hint: what is error in that sampling distribution that represents this populationyou have all the information you need here)

5.A random sample of n = 40 scores is selected from a population. Based on this information alone, do I know that the distribution of samples means will be normal? Why or why not?
