The standard deviation of the sampling distribution of the means is called the:

The standard deviation of the sampling distribution of the means is called the:
 
  a. variance.
  b. standard score.
  c. standard error.
  d. confidence interval.

Question 2

The Central Limit theorem states that:
 
  a. if many samples are drawn randomly from a population, their means tend to be normally distributed.
  b. the means of large samples will be better measures of central tendency than the means of small samples.
  c. most scores will fall within three standard deviations of the mean.
  d. the standard error of a distribution is limited by its central tendency.
