Question 1: The Central Limit Theorem states that the sampling distribution of means is:

a) only available by inference

b) only available when sample sizes are less than 10

c) only available when the very high and very low means have been eliminated

d) approximately normal in shape

Question 2: The z test may be used to determine

a) if the sample is representative of a known population

b) if a sample contains bias

c) the exact amount of sampling error contained in the parameter mean

d) the amount of sampling error contained in the population's standard deviation
