1.Assuming that we randomly draw 5,000 sample means from a population. The sample means will follow:

a.Normal distribution

b.Not enough information

b.Random distribution

c.Uniform distribution

2.If sample mean is 15.6, standard error is 1.7, t score is 2.78, what is the confidence limit?

3.What is the degree of freedom for a sample mean?

4.What is the standard error for the sample mean? How is that different from the sample's standard deviation? (use one to two sentences to answer)

5.What is difference between the population mean and the sample mean?
